How to Build a Content Engine That Actually Works (Using AI)

Published: March 10, 2026Leave a Comment

Everyone has a content strategy now. Every competitor, every agency, every solopreneur with a laptop and a ChatGPT subscription is publishing blog posts, LinkedIn carousels, and email newsletters. The volume of content online hasn’t just increased — it’s exploded.

And most of it is forgettable.

AI made content creation cheap and fast, which means the bar to publish dropped to zero. That’s great if you want quantity. It’s a problem if you want results. The businesses that will win the content game over the next five years aren’t the ones publishing the most — they’re the ones that people actually remember and trust.

Trust is earned through consistency, point of view, and proof. You show up regularly. You have opinions. You’ve actually done the thing you’re writing about. That’s it. That’s the whole game. Everything else is execution.

Here’s how I think about building a content engine that earns trust rather than just adds noise.

The Two-Layer System: Hero and BAU

I split content into two categories, and treating them the same is one of the most common mistakes I see.

Hero content is the big stuff. Quarterly, high-effort, genuinely original. Think original research, comprehensive guides, big campaign pieces that generate attention and bring new people into your orbit. These take time to produce and they should. A hero piece earns coverage, backlinks, and word of mouth.

BAU content — Business As Usual — is the weekly drumbeat. Articles, social posts, newsletters, short-form updates. This is what keeps existing readers engaged between hero moments. BAU keeps you present in people’s minds so that when they need what you offer, your name comes up first.

The ratio matters: one great piece per quarter that attracts new people, and consistent weekly output that nurtures the ones already paying attention. Hero without BAU is a one-hit wonder. BAU without hero is background noise. You need both.

What Good BAU Actually Looks Like

Most content operations that fail do so in the BAU layer. They publish when someone has time, the writing sounds like it could’ve come from any company in the industry, and nothing builds on anything else. It’s disconnected content that doesn’t compound.

Good BAU has four characteristics:

  • Consistent rhythm. A fixed schedule that matches your actual capacity. It’s better to commit to one piece per week and stick to it than to aim for five and go silent every third week. Silence is the trust-killer.
  • Sounds like you. Your audience can tell the difference between content written by a person with a genuine perspective and content assembled from a template. The former builds trust. The latter gets scrolled past.
  • Mixes formats. Long-form articles, short social posts, emails, case studies, quick takes. Different formats reach different people in different moods.
  • Builds on itself. Your content should form a body of work, not a pile of unrelated pieces. Ideas reference each other, themes recur, positions deepen over time.

The Four Mechanics You Need

A content engine has moving parts, and if you haven’t defined them explicitly, you’re improvising. Improvisation doesn’t scale.

1. Content Pillars

Pick three or four themes you’ll return to repeatedly. These are the topics where your expertise is genuine and your perspective is distinct. For me, that’s WordPress/plugin businesses, entrepreneurship, AI and automation, and occasionally personal development. Everything I publish connects to at least one of those.

Pillars create coherence. They also make content planning far easier because you’re not staring at a blank page wondering what to write about — you’re asking which pillar this idea fits into.

2. Source Bank

This is a running document where you log raw inputs: client conversations that revealed something interesting, a problem you keep seeing repeated, an industry observation that annoyed you, something that worked better than expected. Any time something catches your attention professionally, it goes in the source bank.

The source bank solves the “I don’t know what to write about” problem permanently. You’re not generating ideas from nothing — you’re capturing what’s already happening around you and extracting content from it later.

3. Rhythm

Decide on a fixed publishing schedule and treat it like a meeting you can’t cancel. Weekly is the minimum for building audience memory. The specific day doesn’t matter much — consistency matters more than timing.

The most common failure mode I’ve seen (and made myself) is overcommitting. If you can realistically produce two pieces of content per week with your current capacity, commit to one. Then hold it.

4. Production Process

Write down who does what and when. Even if it’s just you. A documented process means content production isn’t dependent on someone being in the right mood or having a clear morning — it’s a sequence of steps that happens on schedule.

The 4-Step Production Process I Use

Every piece of content I produce runs through a version of this:

  1. Start with what’s already happening. What am I dealing with right now? What conversations keep coming up? What problems am I explaining to people repeatedly? The best content comes from lived reality, not from “content ideation.”
  2. Run it through an audience lens. Why would this matter to the people I’m trying to reach, right now? I look for confusion in the market, friction my audience is experiencing, things that have changed that people haven’t caught up with yet, or a pattern I keep recognizing that they probably don’t see yet.
  3. Extract the point of view. What do I actually believe about this topic? Where is the tension? What’s the thing most people get wrong? What am I in a better position than most to explain? If I can’t answer these questions, the piece isn’t ready to write yet.
  4. Translate once, distribute many times. One core input becomes multiple content pieces. A long-form article becomes two LinkedIn posts, an email newsletter, and a series of short takes. A case study becomes social proof, a carousel, and a sales enablement piece. AI is genuinely useful here — the repurposing and format-switching is exactly the kind of mechanical work it handles well.

The Interview Hack

Here’s the problem with building your own content engine: you’re too close to your own expertise. The things that make you genuinely valuable and distinctive feel obvious to you, so you don’t write about them. You assume everyone knows what you know. They don’t.

The fix is to have someone else interview you, or if you’re building this for a team, to interview the people with the expertise. The interviewer asks questions that surface the non-obvious:

  • What’s the most interesting problem you’ve solved recently?
  • What do you keep having to explain to people that they consistently get wrong?
  • What’s changed in your space that most people haven’t caught up with yet?
  • What mistake do you see people making over and over?

Record the conversation. Transcribe it. Run the transcript through AI to extract content pieces. From one forty-five minute interview, you can produce a long-form article, three to four social posts, an email, and pull-quote graphics. The raw material comes from what you actually know, not from AI hallucinating expertise you don’t have.

The interview format works because good questions unlock things you wouldn’t have thought to write about directly. It bypasses the blank-page problem and bypasses the curse of knowledge at the same time.

Standing Out When Everyone Has the Same Tools

If your content looks like solid industry content, it will blend in. That’s the paradox. The more you optimize for “good” by conventional standards — well-structured, properly researched, covers all the bases — the more it sounds like every other piece of good content.

The audience tolerance for content has shifted. The bar isn’t set by other industry blogs — it’s set by the creators people follow for entertainment and education in their personal lives. Podcasters, YouTubers, newsletter writers who have built loyal audiences. Those are the creators your readers are comparing you to, consciously or not.

Think about format, not just topic. Is there a repeating structure you can own? A series? A consistent hook or opening move? Some formats that tend to break through: serialized deep-dives where you follow something over time, scorecards or audits people can apply to their own situation, behind-the-scenes looks at actual work in progress, and video formats where your personality does work that text can’t.

Measuring What Matters

Vanity metrics are easy to track and mostly useless. Follower counts, page views, impression numbers — they don’t tell you if the content is working. Here’s what I actually watch:

  • Engagement quality: Replies, forwards, and comments that indicate someone actually read and thought about what you wrote. One thoughtful reply beats a hundred likes.
  • Source quality: Which channels are bringing in leads that actually close? Content that generates traffic that never converts isn’t working, regardless of the traffic numbers.
  • Nurture effectiveness: How are conversion rates and time-to-opportunity changing for people who consume your content before buying?
  • Production consistency: Are you hitting your publishing schedule? This one is unglamorous but it’s the foundation everything else sits on.

The engine is working when content is publishing on schedule, your audience is growing slowly and steadily, and you can trace closed deals back to content touchpoints. That’s the goal. It takes longer than most people are willing to wait, which is exactly why it’s worth doing.

Where AI Actually Fits

AI isn’t a shortcut to good content — it’s a multiplier on the good inputs you bring to it. Use it to transcribe interviews, switch formats, repurpose a long-form piece into social posts, generate headline options, or edit for clarity. Let it handle the mechanical work so your time goes toward thinking, experiencing, and forming the opinions that make the content worth reading.

The biggest mistake I see people make with AI and content is skipping the “what do I actually know and think” step and going straight to “write me a post about X.” The output is fine. Nobody will remember it.

The businesses that will look back in five years and feel good about their content investment are the ones that used AI to scale a genuine point of view, not the ones that used it to fill a publishing calendar with forgettable text.


On that note — I’m building AgentVania, an AI agent platform that helps small businesses automate operations they’d otherwise need to hire for. Content repurposing is one use case, but it handles everything from customer communication to data processing. It’s early but it’s the kind of infrastructure I wish I’d had years ago. If that sounds relevant to what you’re working on, take a look.

Should You Buy Ethereum Right Now?

Published: March 09, 2026Leave a Comment

Ethereum

Ethereum is the second-largest cryptocurrency by market cap, and that ranking isn’t an accident. It’s earned. While Bitcoin has settled into its role as digital gold, Ethereum has built something categorically different: a programmable platform that underpins a sprawling ecosystem of decentralized finance, smart contracts, and tokenized assets.

I hold ETH as part of my crypto portfolio alongside Bitcoin. But I think about them differently, and I invest in them for different reasons. If you’ve already read my article on buying Bitcoin, you’ll know the Bitcoin thesis is primarily about sound money and censorship resistance. The Ethereum thesis is about something else entirely.

This article covers what Ethereum actually is, why the investment case remains compelling in 2026, what the real risks are, and how to buy it if you decide to.

Bitcoin vs. Ethereum: Why They’re Not the Same Bet

The most common mistake people make when approaching crypto is treating Bitcoin and Ethereum as interchangeable. They’re not. They solve different problems and attract different kinds of users and investors.

Bitcoin is designed to do one thing extremely well: store value in a way that’s decentralized, predictable, and resistant to censorship or debasement. It has a fixed supply of 21 million coins. It doesn’t change much. That’s a feature, not a bug.

Ethereum is a programmable platform. Developers deploy code on it — called smart contracts — that run exactly as written, without the possibility of downtime, censorship, or interference from a third party. That code powers decentralized exchanges, lending protocols, stablecoins, NFT markets, and an increasingly large slice of the traditional financial system that’s migrating on-chain.

Think of it this way: Bitcoin is digital gold. Ethereum is the infrastructure layer for a new internet of value.

What Ethereum Has Built Since 2022

A lot has happened in the Ethereum ecosystem since 2022. If your mental model of ETH is still shaped by that era — high gas fees, Proof-of-Work mining, the Merge as an upcoming event — it’s worth updating.

The Merge Is History

In September 2022, Ethereum completed its transition from Proof-of-Work to Proof-of-Stake. This was one of the most technically complex upgrades ever executed on a live, high-value blockchain network. Energy consumption dropped by roughly 99.95% overnight. The “Ethereum is bad for the environment” criticism, which had some legitimacy before, largely evaporated.

This matters for more than environmental optics. Proof-of-Stake is the foundation that makes staking yields possible, and it changed Ethereum’s issuance model significantly.

Staking Withdrawals, Lower L2 Fees, and the EIP-1559 Burn

The Shanghai/Capella upgrade in April 2023 unlocked staking withdrawals, completing the Merge’s full picture. Validators who had been locked in since the Beacon Chain launch in 2020 could finally exit positions or compound rewards. This removed a significant source of uncertainty from the staking market.

In March 2024, the Dencun upgrade introduced proto-danksharding (EIP-4844), a change specifically designed to reduce costs for Layer 2 networks. Transaction fees on L2s like Arbitrum and Base dropped dramatically — in many cases by 80-90%. Everyday users transacting on Ethereum’s L2 ecosystem now pay cents, not dollars.

EIP-1559, implemented in 2021, introduced a fee-burning mechanism that destroys a portion of transaction fees rather than paying them to validators. During periods of high network activity, Ethereum can actually become deflationary — more ETH burned than issued. This changes the supply dynamics in ways that have no parallel in Bitcoin’s fixed-issuance model.

The L2 Ecosystem Explosion

The most important development in the Ethereum ecosystem over the past two years has been the explosion of Layer 2 networks. These are separate chains that batch and settle transactions on Ethereum mainnet, inheriting its security while running faster and cheaper.

The leading L2s as of 2026:

  • Base — Coinbase’s L2, now the clear TVL leader with roughly 46% of all L2 DeFi activity. It’s where the majority of new retail liquidity has concentrated.
  • Arbitrum — The OG L2, holding around 31% of L2 DeFi TVL. Deep liquidity, mature DeFi ecosystem, institutionally trusted.
  • Optimism — Home of the Superchain initiative, building a network of interoperable rollups.
  • zkSync and StarkNet — Zero-knowledge rollups that offer stronger cryptographic security guarantees.

All of this activity settles on Ethereum mainnet. L2s aren’t competition to Ethereum — they’re its execution layer. The more activity on L2s, the more fees flow back to Ethereum validators and the more ETH gets burned.

Spot ETFs in the US

The SEC approved spot Ethereum ETFs in May 2024, with trading beginning on July 23, 2024. By the end of 2024, ETH ETFs had pulled in $12.6 billion in net inflows, and a further $9.6 billion came in during 2025 alone. Institutional access to ETH through traditional brokerage accounts is now a reality, not a future aspiration.

More recently, regulatory barriers around staking in ETFs have begun to dissolve. ETH ETF products that can participate in staking and pass yield to holders are becoming viable, which makes ETH even more attractive as an institutional asset compared to holding it outright.

The Bull Case for Ethereum

Here’s why I hold ETH and why I think the long-term case remains intact.

The Settlement Layer for Everything On-Chain

Ethereum is where the most economically significant on-chain activity ultimately settles. The deepest DeFi liquidity, the most widely used stablecoins, the majority of real-world asset (RWA) tokenization projects — they’re built on Ethereum or its L2 ecosystem. Network effects at this scale are genuinely difficult to displace.

ETH Is a Productive Asset

Unlike Bitcoin, which produces no yield, ETH can be staked to earn rewards from network validation. The current staking yield is approximately 3-4% APR. This isn’t speculative return — it’s compensation for helping secure the network, paid out in newly issued ETH and transaction fees.

For investors accustomed to thinking in terms of cash flow and yield, this matters. ETH has an argument for inclusion in a portfolio that Bitcoin, by design, doesn’t make.

Institutional Adoption Is Accelerating

The ETF approvals opened the door, and institutions are walking through it. Real-world asset tokenization — putting US Treasuries, real estate, private credit, and other traditional instruments on-chain — is growing rapidly on Ethereum. BlackRock’s BUIDL fund, one of the largest tokenized money market products, lives on Ethereum mainnet. Where institutional money settles, more tends to follow.

Restaking and New Primitives

EigenLayer introduced restaking, allowing validators to use their staked ETH to simultaneously secure other protocols and earn additional yield. This is a nascent area with real risks — but it illustrates that Ethereum’s architecture continues to generate new economic primitives that expand the utility of the asset.

The Bear Case and Real Risks

I try to be honest about risk. Here’s what can go wrong with an ETH investment.

Solana Is a Genuine Competitor

Solana processes transactions directly on its base layer at high throughput and extremely low cost. It has over 3.6 million daily active addresses versus Ethereum’s roughly 530,000. The developer ecosystem is growing fast, and Solana now has its own spot ETFs in the US. For retail-facing, high-frequency applications, Solana is often the more pragmatic choice for developers.

The counterargument is that Ethereum’s total throughput, including L2 activity, surpasses Solana’s. And Ethereum’s institutional liquidity and security track record are significantly deeper. But dismissing Solana as irrelevant would be a mistake.

ETH Has Underperformed BTC in Recent Cycles

If you bought ETH instead of BTC over the past couple of years, you generally would have done worse on a pure price basis. The “flippening” — the idea that Ethereum would eventually overtake Bitcoin in market cap — has cooled considerably as a near-term narrative. Bitcoin’s market cap sits at roughly $1.33 trillion; Ethereum’s is around $235 billion. That gap isn’t closing quickly.

Complexity and Fragmentation

The proliferation of L2s creates a fractured user experience. Bridging assets between chains, managing different networks in a wallet, and understanding which chain your assets actually live on remains genuinely confusing for new users. This friction slows adoption and creates security risks for people who don’t understand what they’re doing.

Regulatory Uncertainty Around Staking

The SEC has previously taken the position that staking services constitute unregistered securities offerings. While the regulatory environment has improved under the current administration, staking — both individual and protocol-level — remains an area where rules are still being written. This could affect yield products and staking-enabled ETFs down the line.

How to Buy Ethereum

Buying ETH is straightforward. The same exchanges I’d recommend for Bitcoin work equally well for Ethereum.

  • Coinbase — The most beginner-friendly option. Regulated US exchange, direct credit card and bank transfer support, and the company behind Base, Ethereum’s leading L2.
  • Binance — The highest global trading volume, competitive fees, and a wide range of pairs. More suitable for users who know what they’re doing.
  • Kraken — Strong security reputation, regulated in multiple jurisdictions, good for European users in particular.

If you’re buying to hold long-term, keep your ETH off exchanges and onto a hardware wallet. Ledger is the standard recommendation — it supports ETH natively and works with the MetaMask browser extension if you want to interact with DeFi or L2 applications.

The ETF Option

If you’d rather hold ETH inside a brokerage account without managing private keys, the spot ETH ETFs — from BlackRock (ETHA), Fidelity (FETH), and others — are a legitimate option. You give up yield, self-custody, and direct on-chain access, but you gain simplicity and the ability to hold ETH in an IRA or standard brokerage account.

Staking Your ETH

One of the things that distinguishes ETH from Bitcoin as an investment is that your ETH can work for you while you hold it. The current yield is around 3-4% APR. Here’s how to do it.

Through an Exchange

The easiest option. Coinbase, Kraken, and Binance all offer staking products where you deposit ETH and receive yield automatically. The tradeoff is that you’re trusting the exchange with your keys — the same custodial risk that applies to holding crypto on any exchange.

Liquid Staking (Recommended for Most People)

Lido and Rocket Pool are the two leading liquid staking protocols. You deposit ETH and receive a liquid staking token (stETH from Lido, rETH from Rocket Pool) that represents your staked ETH plus accrued rewards. This token can be used in DeFi or simply held. Rocket Pool is more decentralized; Lido is larger and more liquid.

Liquid staking is the middle ground between exchange convenience and true self-custody. You’re not dependent on an exchange, and your staking position remains liquid.

Solo Staking (Advanced)

Running your own validator node requires 32 ETH and technical competence. You take on full responsibility for uptime and security, but you also take no platform risk and receive the full staking yield directly from the protocol. Not for most people, but the most trust-minimized option.

My Take

I hold ETH because I think Ethereum is the most likely candidate to become the base layer for a significant portion of global financial activity over the next decade. That’s a long-horizon bet, and it comes with real volatility and real uncertainty.

It’s a different thesis from Bitcoin. Bitcoin is the harder, simpler bet — sound money with a fixed supply and maximum security. Ethereum is the more complex bet on a platform, an ecosystem, and a developer community that has, despite skepticism, continued to execute.

Both can win. They’re not mutually exclusive, and I think about them as complementary positions in a crypto allocation rather than an either/or choice.

If you’re considering buying ETH: do your own research, understand what you’re buying, and only allocate what you can afford to hold through a significant drawdown. Crypto is volatile, and Ethereum is no exception. But the underlying technology and ecosystem are more mature than they’ve ever been.

Should You Buy Bitcoin Right Now?

Published: March 09, 2026Leave a Comment

Bitcoin

Every time Bitcoin makes headlines — whether it’s crossing a new milestone or going through one of its trademark corrections — my inbox fills up with the same question: should I buy Bitcoin right now?

I’ve been answering some version of this question since 2013. My answer has stayed consistent, even as the number at the end of the ticker keeps moving.

The short answer: yes, if you have a 5-10 year horizon and understand what you’re buying. Not because I can tell you where the price is going next month, but because I genuinely believe Bitcoin is the best investment opportunity of our generation — and the evidence for that has only strengthened since I last updated this article.

Let me walk you through how I think about it.

How to Buy Bitcoin (If You’re Ready to Get Started)

If you already know you want in and just need a practical starting point, here’s the short version.

The easiest route is a reputable centralized exchange. I’ve used all three of these and recommend them for different reasons:

  • Coinbase — Best for beginners. Clean interface, US-regulated, good mobile app.
  • Binance — Largest exchange by volume. More features, lower fees, better for active users.
  • Kraken — Strong security track record, good for European users, competitive fees.

Sign up, verify your identity (KYC is standard now across all serious exchanges), and buy. That part has never been easier.

Once you’ve bought, the next question is where to keep it. For amounts worth protecting, I’d recommend moving your Bitcoin off the exchange and into a hardware wallet. Ledger is the most widely used. Yes, there’s a learning curve — but leaving significant value on an exchange indefinitely isn’t something I’d be comfortable with.

That said, if you’d rather get exposure without managing custody at all, Bitcoin spot ETFs are now an option. More on that below.

Don’t Try to Time the Market

This is the part most people want to skip, but it’s the most important thing I can tell you.

I don’t try to call market bottoms. I don’t wait for the “perfect” entry. I’ve been buying Bitcoin at various price points over the years — some in hindsight looked like brilliant timing, others looked terrible in the short term. Over a multi-year horizon, the price I paid on any given day has mattered much less than the decision to buy and hold at all.

If the uncertainty of lump-sum investing keeps you on the sidelines, use dollar-cost averaging instead. Set up automatic monthly purchases — $100, $500, whatever fits your situation — and remove the emotional decision-making entirely. You’ll buy some at highs and some at lows, and over time that averages out into a sensible cost basis.

The mistake I see repeatedly is people waiting for a correction that either doesn’t come, or comes and then they still don’t buy because it feels like it might drop further. Meanwhile, the asset they were waiting to buy is significantly higher than when they started watching it.

If your thesis is long-term and fundamental — which mine is — the entry point matters far less than most people think.

Why I’m Still Bullish in 2026

Let me lay out the fundamental case, updated for where we are now.

The scarcity argument hasn’t changed — and never will

There will only ever be 21 million Bitcoin. That’s not a policy. It’s code that thousands of nodes around the world enforce simultaneously. No central bank, no government, no company can change it unilaterally.

Meanwhile, every major fiat currency on earth continues to be inflated by its issuing government. The purchasing power erosion from 2020-2022 alone made this point viscerally clear to a lot of people who had previously dismissed it as abstract.

Bitcoin’s fixed supply against an expanding money supply is the core of the investment thesis, and it hasn’t weakened.

The stock-to-flow model held

When I wrote the original version of this article, I cited the stock-to-flow model and Bitwise’s “fourth era” prediction of Bitcoin reaching $100,000 or more. At the time, Bitcoin was trading around $30,000-$40,000 and those predictions seemed bold to many people.

Bitcoin crossed $100,000 in late 2024 and has consolidated above that level. The Kraken wealth transfer report I referenced previously predicted Bitcoin reaching $70,000 by 2044. It surpassed that figure decades ahead of schedule.

I’m not saying price models are gospel. But the directional thesis — that Bitcoin’s value would continue to appreciate as adoption grew and supply became increasingly scarce — played out.

The halving keeps doing its job

The April 2024 halving reduced the block reward from 6.25 BTC to 3.125 BTC. This happens every four years, programmatically cutting the rate at which new Bitcoin enters circulation. Historically, halvings have preceded significant bull runs, and the current cycle has followed that pattern.

The next halving is in 2028. If you’re investing with a 5-10 year horizon, that’s relevant context.

Institutional adoption is no longer a prediction — it’s a fact

In January 2024, the SEC approved Bitcoin spot ETFs in the United States. This was a landmark moment. BlackRock, Fidelity, and several other major asset managers now offer regulated Bitcoin investment products to institutional and retail investors alike.

The significance of this can’t be overstated. These firms collectively manage trillions of dollars in assets. Even modest portfolio allocations to Bitcoin ETFs represent enormous demand against a fixed and slowly growing supply. BlackRock’s Bitcoin ETF became one of the fastest-growing ETFs in history within months of launch.

When I was writing about Bitcoin in 2013 and 2017, the institutional question was entirely speculative. That’s no longer true.

Regulatory clarity is improving

Europe’s MiCA (Markets in Crypto-Assets) regulation came into full effect in 2024, providing a comprehensive legal framework for crypto across EU member states. That’s 27 countries with clear rules — a significant shift from the patchwork of uncertainty that existed before.

El Salvador made Bitcoin legal tender back in 2021, and other countries have been exploring similar moves. Regulatory direction, broadly speaking, has moved toward accommodation rather than prohibition in the major economies.

There’s still uncertainty in some jurisdictions, particularly around tax treatment and specific use cases. But the narrative that governments would simply ban Bitcoin has become increasingly implausible — especially now that US-regulated ETFs exist from companies like BlackRock and Fidelity.

The energy FUD has weakened considerably

Bitcoin mining uses energy. That’s true and worth acknowledging. But the narrative that Bitcoin is an environmental catastrophe has been significantly undermined by the data that’s emerged over the past few years.

A growing proportion of Bitcoin mining now runs on renewable energy — stranded hydroelectric, flared natural gas that would otherwise be vented into the atmosphere, and purpose-built renewable installations. The economic incentive to use the cheapest available electricity naturally drives miners toward stranded or excess capacity, much of which is renewable.

This doesn’t make Bitcoin “green” in a simple sense. But the one-dimensional “Bitcoin wastes energy” argument is far weaker than it was a few years ago.

The Hurdles That Remain

I’m bullish, but I’m not dismissive of the real challenges. Anyone considering a significant allocation should think honestly about these.

Custody is still complicated

Self-custody has gotten easier — hardware wallets are more user-friendly, and there’s better documentation and tooling than there used to be. But it’s still not something you can do carelessly. Lose your seed phrase with no backup, and your Bitcoin is gone. There’s no customer support, no password reset, no recourse.

For people who want exposure without the responsibility of custody, Bitcoin ETFs now provide a legitimate alternative. You give up the sovereignty and the self-sovereign ethos, but you gain simplicity and regulatory protection. That tradeoff is worth naming clearly.

Volatility is real and won’t disappear soon

Bitcoin has dropped 50-80% multiple times in its history, often from all-time highs. It has always recovered and gone on to new highs — but the recoveries have taken months to years. If you buy and the price drops 60% next month, can you hold without selling? If the honest answer is no, you should either reduce your position size or reconsider the timeline.

This isn’t a reason not to invest. It’s a reason to invest only what you can afford to leave alone for years.

Correlation with tech stocks

One argument for Bitcoin has always been its low correlation with traditional asset classes — the digital gold narrative. In practice, during risk-off periods (rising interest rates, liquidity crunches), Bitcoin has tended to sell off alongside tech stocks rather than behaving as an uncorrelated safe haven.

This may change as the asset matures and more of its holders are long-term institutional allocators rather than leveraged speculators. But it’s worth knowing that Bitcoin is not yet a reliable hedge against equity market downturns.

Regulatory uncertainty in specific jurisdictions

MiCA has clarified things in Europe. The US now has regulated ETFs. But tax treatment, reporting requirements, and specific rules vary significantly by country and continue to evolve. If you’re holding meaningful amounts, you need to understand the rules in your jurisdiction — and ideally talk to an accountant who actually understands crypto.

Ways to Get Exposure

There are now several legitimate ways to hold Bitcoin, each with different tradeoffs.

Buy and hold on an exchange

The simplest starting point. Buy on Coinbase, Binance, or Kraken, and keep it there while you get comfortable. Not ideal long-term (exchange risk, not your keys), but fine for smaller amounts while you learn.

Self-custody with a hardware wallet

Move your Bitcoin off the exchange into a Ledger or similar hardware wallet. You control the private keys. This is the sovereign approach — and the one that aligns with Bitcoin’s original design. It requires more responsibility but gives you genuine ownership.

The Lightning Network has also matured significantly for smaller transactions. If you want to actually use Bitcoin for payments rather than just hold it, Lightning makes that practical in a way that on-chain transactions don’t at current fees.

Bitcoin spot ETFs

If you invest through a brokerage account and don’t want to deal with wallets, seed phrases, or exchange accounts, a Bitcoin ETF is now available. BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) are the largest. You get price exposure through a familiar, regulated wrapper. You don’t get the Bitcoin itself — but for a retirement account or a brokerage portfolio, this is a meaningful option that didn’t exist two years ago.

Tax Considerations

Taxes on Bitcoin vary significantly by country, and this is one area where getting it wrong is expensive. A few principles that apply broadly:

  • In most countries, selling Bitcoin for fiat is a taxable event — capital gains apply.
  • Buying Bitcoin is generally not taxable.
  • Exchanging Bitcoin for another cryptocurrency is often treated as a taxable disposal.
  • Some jurisdictions treat Bitcoin payments for goods and services as taxable events at the time of transaction — which is one reason why everyday Bitcoin spending remains awkward.

Portugal has historically been favorable for crypto holders, treating gains as tax-free under certain conditions — though the rules have evolved, so check the current situation. I’ve written more about this in my article on Portugal’s crypto tax rules.

For a broader overview of crypto taxes, see this article. And if you’re holding significant amounts, please talk to an accountant. The complexity and stakes are both high enough to justify professional advice.

Still Early. Still Clear.

Bitcoin crossed $100,000. The ETFs launched. BlackRock and Fidelity are in the market. MiCA is law. The halving happened. Every major prediction I was tracking when I wrote the original version of this article has come true or is on track.

And yet I still think we’re early. Not in the “Bitcoin will 100x” hyperbole sense — I’m not making price predictions. But in the sense that Bitcoin’s role as a global reserve asset, a savings technology for people in weak-currency economies, and a store of value sitting alongside gold in institutional portfolios is still being established. The infrastructure, the regulatory frameworks, the mental models — all of it is still being built.

My personal approach hasn’t changed: I believe in Bitcoin and hold it as part of my net worth. I don’t trade it, and I don’t lose sleep over the short-term price movements. I’m not waiting for the right moment, because I don’t believe in timing markets — and because I think the right moment was years ago and the second-best time is now.

If you believe, as I do, that sound money matters, that scarcity has value, and that the current financial system’s structural problems aren’t going away — Bitcoin is the clearest expression of that belief you can make with your savings.

Do your own research. Understand what you’re buying. Size your position appropriately. And take a long view.

A Simple Payment Card Strategy for Running an Online Company

Published: March 07, 2026Leave a Comment

bank card strategy for small company

A few years ago, an employee left and I discovered their card was attached to our hosting, three AI tools, and the domain registrar. Cancelling the card triggered a chain of failed payments that took days to untangle. Some services suspended without warning. One nearly deleted our data after a grace period I didn’t know about.

That week I set up a proper card system. It took about an hour and I haven’t had a billing emergency since.

If you run a small online company, you probably pay for dozens of services — hosting, SaaS tools, ad platforms, AI APIs, domain registrars. Payment cards are the plumbing behind all of it, and most people don’t think about them until something breaks. Here’s how to make sure it doesn’t.

Default to Virtual Cards

Physical cards are mostly irrelevant for an online business. Nearly everything you pay for — cloud infrastructure, subscriptions, developer tools, advertising — is billed online.

Virtual cards are better in every way for this. You can create them instantly, freeze them in seconds, and delete them without affecting anything else. If one is compromised, the blast radius is limited to whatever that card was used for.

Setting This Up in Revolut and Wise

The two platforms I’ve used most for this are Revolut Business and Wise Business. Both support virtual cards and work well for this system, but they handle things differently.

Revolut Business is the more polished option for managing multiple cards. You can create virtual cards instantly, assign them labels, set per-card spending limits, and freeze or delete them from the app. Creating the four-card setup described above takes minutes. Revolut also gives you a clearer dashboard for tracking spend across cards, which makes the periodic review easier.

Wise Business supports virtual cards too, but the experience is simpler. You can create cards linked to specific currency balances, which is useful if you pay for services in multiple currencies and want to avoid conversion fees. Wise’s per-card controls are more basic — you can freeze and delete, but spending limits per card aren’t as granular as Revolut’s.

In short: Revolut is better if you want tight control over multiple cards with detailed limits. Wise is better if you deal with multiple currencies and want to hold and pay in each directly. Many small companies end up using both.

If your current bank doesn’t offer virtual cards at all, either of these is a significant upgrade. I’ve written more detailed reviews of both Revolut and Wise if you want to dig deeper.

Don’t Let Cards Depend on People

One of the most common mistakes is letting employees attach their company cards to services. It works fine until they leave. Then you cancel the card, billing breaks, and services start getting suspended — sometimes silently.

Cards should be owned by the company account, not by individuals. Store the details in a password manager like 1Password or Bitwarden, organised by purpose. Team members copy the details when they need to add billing somewhere. When someone leaves, nothing changes.

Segment Cards by Purpose

Using a single card for everything feels simpler, but it’s a trap. When that card expires or gets replaced, you’re updating every service you pay for. Miss one and you find out weeks later when something stops working.

Instead, use a small number of cards, each dedicated to a category:

Infrastructure — hosting, cloud platforms, AI APIs, domains, security tools. These are services where a billing failure actually hurts. This card gets the highest limit and the most attention.

SaaS subscriptions — collaboration tools, project management, analytics, productivity apps. Important but less urgent. If billing lapses for a day, nothing catches fire.

Advertising — Google Ads, Meta, and any other ad platforms. Ad platforms have unpredictable billing behaviour — irregular charge amounts, failed payment retries, sudden spend spikes. Isolating them prevents surprises on your other cards.

Experiments — anything you’re trying out. New tools, free trials that ask for a card, services you’re evaluating. Keep a low spending limit on this one. If a forgotten trial converts to a paid plan or something charges unexpectedly, the damage is contained.

With this setup, replacing a card means updating one category of services, not everything.

Keep One Physical Card for the Real World

Even a fully online company has occasional offline expenses — travel, hardware, team meals, conferences. One physical card for the founder covers this. Just don’t use it for subscriptions or recurring payments. Keep it separate from the system above.

Set Limits and Review Regularly

Most fintech platforms let you set spending limits per card. Use them. A low cap on the experiments card and a reasonable cap on SaaS prevent the slow accumulation of forgotten charges.

It’s also worth reviewing your SaaS card transactions every few months. Tools accumulate. Trials convert. Teams stop using things but nobody cancels them. A quick audit usually turns up a few subscriptions that can be cut.

The Full Setup

For most small online companies, this is all you need:

  • 3–4 virtual cards segmented by purpose
  • 1 physical card for offline spending
  • All cards owned by the company, not individuals
  • Details stored in a shared password manager vault

It takes about an hour to set up and saves you from a class of problems that are annoying, disruptive, and entirely preventable.

Aftermarket Parts for the Traxxas TRX-4M: A Brand-by-Brand Guide

Published: February 26, 2026Leave a Comment

The Traxxas TRX-4M took the RC crawling world by storm as a 1/18-scale trail truck that punches well above its weight class. Its compact size, portal axles, and surprisingly capable suspension made it an instant hit — and it didn’t take long for the aftermarket to respond. Whether you’re chasing better trail performance, durability, or just want your mini crawler to stand out, there’s no shortage of upgrades available. Here’s a breakdown of where to find them and which brands are leading the way.

Electronics & Power

Furitek

Furitek has become practically synonymous with mini crawler electronics. Their Lizard Pro and Lizard V2 brushless ESCs are purpose-built for 1/18 and 1/24-scale crawlers, offering drag brake tuning, proportional throttle control, and smooth low-speed crawling that the stock Traxxas ESC simply can’t match. Pair one with a Furitek Micro Komodo or Stinger brushless motor and the TRX-4M transforms into a completely different machine. They also sell combo kits that include the ESC, motor, and wiring harness pre-configured for the TRX-4M, taking the guesswork out of the swap.

Emax

For those looking at servo upgrades, Emax offers micro servos like the ES08A II that fit the TRX-4M’s tight chassis dimensions and deliver noticeably faster, stronger steering response than the stock unit.

Aluminum & CNC-Machined Upgrades

Treal Hobby

Treal has arguably the widest catalog of CNC aluminum and brass parts specifically designed for the TRX-4M. Their offerings include aluminum portal housings, steering links, shock towers, chassis rails, and transmission cases — all precision-machined and available in multiple anodized colors (black, red, blue, titanium, and more). Their brass portal covers and knuckles are especially popular because they add weight exactly where crawlers need it most: down low and at the axles. Treal sells direct through their website and Amazon, and pricing sits in a competitive middle ground between budget and premium.

Hot Racing

Hot Racing is a veteran name in RC upgrades and their TRX-4M line doesn’t disappoint. They produce aluminum shock bodies, sway bar kits, steering links, and drive shafts. Their parts tend to be slightly more premium in finish and fitment. The aluminum front and rear bumper/skid plate combos are particularly well-regarded for both looks and protection. Available through most major hobby retailers including AMain Hobbies and Amazon.

Meus Racing

Meus Racing has been steadily building a following in the mini crawler community with a broad and affordable parts catalog for the TRX-4M. They cover a lot of ground — aluminum suspension links, shock towers, skid plates, portal housings, steering components, and chassis braces — all CNC-machined and offered in multiple anodized color options. Where Meus Racing particularly stands out is in their scale and functional accessories: detailed roof racks, side step bars, bumpers with shackle mounts, and even full chassis rail conversion kits. Their brass upgrade parts (diff covers, portal knuckle weights, and axle-mounted counterweights) compete directly with Treal and Injora on both quality and price. They also offer complete upgrade bundles that package multiple parts together at a discount, which is appealing if you’re doing a full build rather than upgrading one piece at a time. Most of their catalog is available through Amazon and their own storefront. Meus Racing occupies a sweet spot — more variety than GPM with quality that competes with Treal, all at accessible pricing.

GPM Racing

GPM offers a massive selection of aluminum replacement parts at aggressive price points. Nearly every stock plastic component on the TRX-4M has a GPM aluminum equivalent — knuckles, C-hubs, shock mounts, body posts, even the differential cover. Quality can vary piece to piece, but for the price they represent solid value, especially if you’re upgrading the entire truck at once. Widely available on Amazon and eBay.

Brass & Weight Additions

Injora

Injora has built a strong reputation in the mini crawler community for affordable brass and aluminum upgrades. Their brass portal covers, counterweights, and wheel weights are among the most popular TRX-4M parts sold online. They also offer complete brass axle housing sets, skid plates, and steering components. Beyond metal parts, Injora carries a full range of wheels, tires, body shells, and scale accessories specifically sized for the TRX-4M. Their direct website often has bundle deals, and their Amazon storefront makes ordering easy.

Yeah Racing

Yeah Racing produces brass diff covers, portal housings, and link sets for the TRX-4M. Their parts are well-machined and competitively priced. They’re a solid middle-of-the-road option if you want quality brass without paying top dollar.

Bodies & Shells

Bitty Design

Bitty Design is an Italian company known for high-quality polycarbonate body shells across multiple RC scales, and they’ve brought that expertise to the TRX-4M. Their Rock Lizard 1/18 crawler body is a standout — a purpose-designed crawling shell with aggressive lines, proper wheel clearance, and scale detailing that looks fantastic on the TRX-4M chassis. Unlike generic hard bodies, Bitty Design shells are lightweight polycarbonate, which gives you more freedom to add brass weight down low where it matters without making the truck top-heavy. They come clear for custom painting, and the fit and trimlines are precise. Available through most major hobby retailers and their direct website, they’re a premium option for anyone who wants their TRX-4M to look as unique as it performs.

Hobby Details

Hobby Details carries a growing selection of TRX-4M body shells (Bronco, Land Cruiser, Defender styles), LED light kits, and interior components. They’re a good one-stop shop for making your TRX-4M look as good as it crawls, with hard body options that bring serious scale realism to the 1/18 platform.

Tires & Wheels

Injora

In addition to their metal parts, Injora dominates the TRX-4M tire and wheel market. They offer dozens of wheel designs in aluminum and plastic (beadlock and non-beadlock), plus soft-compound tire options in various tread patterns. Their 1.0″ beadlock wheels paired with super-soft sticky tires are one of the most common upgrades and make an immediate difference on rocks and technical terrain.

Powerhobby

Powerhobby produces 1.0″ tires specifically for the TRX-4M class, including the Raptor and Armor patterns that offer excellent grip on multiple surfaces. They also sell wheel and tire combos pre-mounted and ready to bolt on.

RC4WD

RC4WD offers scale-realistic 1.0″ tire and wheel options for those building a more true-to-life rig. Their Mud Plugger and Interco licensed tires bring full-size tire aesthetics down to 1/18 scale, and their stamped steel-style beadlock wheels are hard to beat for realism.

Specialty & Scale Parts

Mofo RC

Mofo RC has carved out a niche with creative, well-designed TRX-4M-specific parts. They’re known for functional accessories like high-clearance skid plates, chassis-mounted servo setups, bumpers, and rock sliders. Many of their parts are designed to solve specific performance problems rather than just look good, which makes them a favorite among serious trail runners. Available through their own website.

Knight Customs (3D Printed)

For scale body accessories — roof racks, light bars, snorkels, fender flares, and interior details — Knight Customs offers an extensive line of 3D-printed parts sized for TRX-4M bodies. They sell through their own storefront, and the level of detail is impressive for the price.

Drivetrain & Hardware

MIP

MIP (Moore’s Ideal Products) makes precision spline drive shafts and CVDs for a range of RC vehicles. Their steel and aluminum drive shafts for the TRX-4M are a worthwhile upgrade if you’re running more powerful brushless setups that put extra stress on the drivetrain.

1UP Racing

For those who obsess over the details, 1UP Racing offers precision bearing kits and premium hardware (titanium screws, anti-wear lubricants) that fit the TRX-4M. A full bearing kit swap reduces friction throughout the drivetrain and is one of the best bang-for-buck upgrades you can make on any RC vehicle.

Where to Buy

  • Amazon — The largest selection from nearly every brand mentioned. Convenient but watch for counterfeit or mislabeled parts from unknown sellers.
  • AMain Hobbies — One of the biggest dedicated RC hobby retailers. Carries Hot Racing, Yeah Racing, MIP, and more with reliable shipping.
  • Jenny’s RC — Well-stocked hobby shop that carries Treal, Furitek, Injora, and many niche brands. Often has parts in stock that bigger retailers don’t.
  • Horizon Hobby — Carries select aftermarket brands alongside Traxxas stock parts.
  • Brand Direct Websites — Treal, Furitek, Injora, Meus Racing, Bitty Design, and Mofo RC all sell directly through their own websites, often with bundle pricing or early access to new releases.
  • eBay — Good for GPM Racing parts and deals on used or overstock items.

Final Thoughts

The TRX-4M aftermarket is remarkably mature for a truck in this size class. Whether you’re spending $10 on a set of brass portal covers or $100+ on a full brushless electronics swap, the upgrade path is deep and well-supported. Start with tires and brass weight — those two changes alone will dramatically improve capability on the trail. From there, electronics and aluminum chassis components let you build a mini crawler that genuinely rivals full-size rigs in technical ability.

The best part? At 1/18 scale, even the premium upgrades are a fraction of what you’d spend on a full-size truck. That makes the TRX-4M one of the most rewarding platforms to build and modify in the hobby today.
