Investing in stocks is one of the most reliable ways to build wealth over time. Not get-rich-quick wealth, but steady, compounding growth that outpaces inflation and builds a real financial cushion over years and decades.

I’ve been investing in the stock market for over a decade now. I’ve made good calls, bad calls, and learned a lot through both. What I’ll share here isn’t theory — it’s the approach I actually use and would recommend to anyone starting out or looking to sharpen their strategy.

This guide is for people who want a sensible, practical framework. Not stock tips, not hype, and not overly academic explanations. Just a clear roadmap for getting started and staying on track.

Why Invest in Stocks at All?

Cash sitting in a savings account loses purchasing power every year. With inflation running at 2-4% annually in normal times — and much higher in recent years — money that isn’t invested is money that’s slowly shrinking.

The stock market, measured by a broad index like the S&P 500, has returned an average of roughly 10% per year before inflation over the long run. After inflation, that’s still around 7% annually. Compounded over 20 or 30 years, those returns are transformative.

This isn’t about gambling or speculation. It’s about putting your savings to work in the most productive engine humans have invented: companies that innovate, grow, and generate profit.

Index Investing: The Foundation of a Smart Portfolio

Here’s a fact that surprises most new investors: the majority of professional fund managers fail to beat a simple stock market index over any 10-15 year period. The S&P SPIVA report consistently shows that 80-90% of active fund managers underperform their benchmark index over 15 years, after fees.

That’s not incompetence. It’s math. Markets are largely efficient, meaning prices already reflect publicly available information. When highly paid analysts with Bloomberg terminals can’t consistently beat the market, the odds that an individual investor doing it in their spare time are slim.

The logical conclusion is to stop trying to beat the market and simply own it. That’s what index investing is: buying a fund that tracks the entire market, giving you a small slice of hundreds or thousands of companies at once.

What Index Funds and ETFs to Look At

For European investors, the most sensible core options are:

• iShares Core MSCI World UCITS ETF (IWDA) — covers over 1,500 large and mid-cap companies across developed markets. Low TER of 0.20%.
• Vanguard FTSE All-World UCITS ETF (VWRL) — includes both developed and emerging markets in one fund. TER of 0.22%.
• iShares Core MSCI Emerging Markets IMI UCITS ETF (EMIM) — useful as a satellite position alongside IWDA for broader global exposure.

For European retail investors, these UCITS-compliant ETFs are the right choice — they’re structured specifically for EU investors and comply with local regulations in a way that US-listed ETFs do not.

A simple two-fund approach of roughly 88% IWDA and 12% EMIM gives you broad global diversification at a combined cost of under 0.20% per year. That’s the kind of simplicity that tends to win over the long run.

The 80/20 Approach: Index Funds Plus a Stock Picking Allocation

I’ll be honest: even knowing all the data on index investing, I still enjoy picking individual stocks. It keeps me engaged with businesses, forces me to think analytically, and every so often it pays off in a way that an index never would.

The solution I’ve landed on is a split approach. Around 80% of my stock market allocation goes into index funds — this is the core, the foundation, the part I don’t touch. The remaining 20% I use for individual stock picks.

This approach has a few real advantages:

• Your core wealth is protected by diversification regardless of whether your individual picks work out
• You stay engaged and keep learning about markets and businesses
• If your stock picks underperform (which is likely over time), the damage to your overall portfolio is contained
• If your picks do well, you benefit from that upside without having gone all-in on speculation

Think of the 20% as tuition. Even in years when those picks lose money, you’re buying something valuable: market knowledge, emotional discipline, and a much deeper understanding of how businesses actually work.

How to Pick Individual Stocks (for Your 20%)

Picking stocks well is hard. Picking them badly is easy and common. Here’s how I approach it.

Understand the Business First

Warren Buffett’s rule is simple: don’t invest in a business you don’t understand. If you can’t explain in plain language what a company does, how it makes money, and why customers choose it over competitors, you shouldn’t own it.

Start with companies in industries you already know. If you work in software, look at software companies. If you’re a pharmacist, you probably have better intuitions about the pharmaceutical space than most analysts. Your professional knowledge is a genuine edge.

Look at the Fundamentals

You don’t need to be an accountant to read a basic income statement. A few numbers worth checking before buying any stock:

• Revenue growth — is the company actually growing year over year?
• Profit margins — does it convert revenue into profit efficiently?
• Debt levels — companies drowning in debt are fragile, especially in downturns
• Price-to-earnings (P/E) ratio — how much are you paying relative to earnings? Context matters here; a high P/E can be justified for fast-growing companies but not for slow-growing ones
• Free cash flow — this is the real money a business generates after expenses. Hard to fake, unlike reported earnings

Invest in Companies You Actually Use

Peter Lynch, one of the best stock pickers in history, advocated for investing in what you know. If you use a product every day and love it, you have real insight into that company’s value proposition that isn’t always reflected in analyst reports.

I’ve made some of my better stock decisions by starting from my own usage patterns and then doing the fundamental work to see if the financials supported the story.

Ignore the Hype

By the time a stock is trending on social media or getting breathless coverage in financial media, the easy gains are usually already gone. Hype-driven investing is how people buy at the top. Reddit threads and Twitter hot takes are entertainment, not research.

The best stock picks tend to be boring, well-understood businesses that the crowd hasn’t gotten excited about yet — or ones that have been temporarily beaten down for reasons that don’t change the long-term thesis.

Key Investing Principles to Live By

Diversify Properly

Putting 50% of your portfolio in one stock is not investing — it’s gambling with extra steps. Real diversification means spreading across companies, sectors, and geographies. This is exactly why index funds do the heavy lifting so well: a single ETF like VWRL gives you exposure to thousands of companies across dozens of countries.

In your 20% stock picking allocation, aim for at least 10-15 individual positions and avoid any single one becoming more than 20-25% of that bucket.

Dollar-Cost Average Instead of Timing the Market

Trying to pick the “right time” to invest is a losing game. Research consistently shows that time in the market beats timing the market. Instead, invest a fixed amount on a regular schedule — monthly, quarterly — regardless of what the market is doing.

This strategy, called dollar-cost averaging, means you automatically buy more shares when prices are low and fewer when they’re high. Over time, it smooths out volatility and removes the emotional paralysis that comes with waiting for the “perfect” moment.

Think in Decades, Not Quarters

The stock market goes up and down constantly. Every few years there’s a significant correction. These are not catastrophes — they’re normal and expected. What matters is where the market is 20 years from now, not next quarter.

Investors who held through the 2008 financial crisis, the 2020 COVID crash, and the 2022 rate-driven selloff all recovered and went on to new highs. Investors who panicked and sold locked in their losses permanently.

Only Invest What You Can Afford to Leave Alone

Don’t invest money you might need in the next two to three years. If you’re investing your emergency fund or a down payment you’ll need soon, you’re exposed to the risk of being forced to sell at exactly the wrong time. Keep three to six months of living expenses in cash or near-cash before you put a euro into the stock market.

Control Your Emotions

Behavioral finance research shows that the average investor significantly underperforms the average fund they invest in — because they buy after markets go up and sell after they go down. The enemy isn’t a bad market. It’s a bad reaction to a normal market.

Having a written investment policy — even a simple one that says “I invest X euros per month into Y funds and don’t sell unless the fundamental thesis changes” — protects you from your own worst impulses during periods of fear or greed.

Where to Invest as a European Investor

Broker choice matters more for Europeans than for US investors, because not all platforms offer the UCITS-compliant ETFs you need, and fees vary significantly.

The two platforms I recommend for European investors are:

DEGIRO

DEGIRO is one of the cheapest brokers available to European investors. It offers access to a wide range of stocks and ETFs across major European and US exchanges, with very low transaction fees. A selection of ETFs are available commission-free on a monthly basis, which makes it ideal for regular index fund investors. DEGIRO is regulated in the Netherlands and covered by the Dutch investor protection scheme.

Interactive Brokers

Interactive Brokers is the broker of choice if you want a more sophisticated setup — options trading, multi-currency accounts, margin, access to more international markets. The interface is more complex than DEGIRO, but the platform is robust, well-regulated, and used by professional traders worldwide. For investors managing larger portfolios or wanting access to US-listed securities alongside European ones, it’s worth the learning curve.

Both platforms are solid choices. For most people starting out, DEGIRO is the simpler and cheaper option to begin with.

Common Mistakes to Avoid

Panic Selling During Downturns

Markets drop. Sometimes sharply. The worst thing you can do is sell your positions during a downturn because you’re scared. Every major crash in history has been followed by a recovery. Selling turns a temporary loss into a permanent one.

Overconcentrating in One Stock or Sector

Even if you’re convinced about a single company or sector, concentration risk is real. Companies that looked invincible have gone to zero. No single position should be able to seriously damage your overall financial picture.

Trying to Time the Market

Even professional investors with sophisticated models consistently fail at market timing. Waiting for “the right moment” almost always means waiting too long. The best time to invest was yesterday. The second best time is today.

Following Social Media Stock Tips

The people shouting loudest about a stock on social platforms are often the ones who already own it and want you to drive the price up. By the time a stock reaches viral status, the informed buyers are already in. Don’t let Reddit or Twitter be your research department.

Neglecting Fees

A 1% annual fee doesn’t sound like much. Over 30 years on a meaningful portfolio, it can cost you tens of thousands of euros in compounding returns lost to fees. Favor low-cost index ETFs with TERs under 0.25%, and avoid any actively managed fund that charges 1.5% or more annually without a compelling, evidence-backed reason.

Checking Your Portfolio Every Day

This sounds harmless but it isn’t. Frequent portfolio checking encourages short-term thinking and emotional decision-making. Set up your monthly investment contributions, check in quarterly to rebalance if needed, and leave it alone in between. The less you tinker, the better your long-term returns tend to be.

Where to Go From Here

The framework is simple: build a core of low-cost index ETFs that give you broad market exposure, add a smaller allocation for individual stock picks if that’s something you enjoy, stay disciplined with regular contributions, and avoid the behavioral mistakes that derail otherwise solid strategies.

You don’t need to be an expert to invest well. You need a clear plan, the right tools, and the discipline to stick with it when markets get uncomfortable — which they will, eventually. That’s the game.

If you’re ready to get started, DEGIRO is a good first platform for European investors. It’s where I started, and it covers everything you need at low cost.

Start investing on DEGIRO

For years, the longevity conversation has been dominated by Zone 2 training — that easy, conversational-pace cardio that builds your aerobic base. And it’s important. But recent research, championed by Dr. Rhonda Patrick among others, suggests we’ve overcorrected. The data on vigorous exercise is striking, and it’s changed how I approach my own training.

I play padel competitively, run, and jump rope alongside my strength training. Here’s what the science says about why the intense stuff matters more than I thought.

The Headline Number: 1 Minute of Vigorous = 4-10 Minutes of Moderate

The most compelling recent study comes from Biswas et al. (2025), published in Nature Communications. Using accelerometer data from roughly 73,000 UK Biobank participants — not self-reported questionnaires, but actual device-measured activity — they found that one minute of vigorous exercise provides the health-equivalent benefit of:

• 4.1 minutes of moderate exercise for all-cause mortality
• 7.8 minutes for cardiovascular mortality
• 9.4 minutes for type 2 diabetes
• 3.5 minutes for cancer mortality

This dramatically exceeds the standard WHO guideline ratio of 1:2 (1 minute vigorous = 2 minutes moderate), which was based on caloric expenditure rather than actual health outcomes. The real-world health equivalence is two to five times higher than what guidelines suggest.

To put that in practical terms: 10 minutes of jump rope may deliver the same mortality benefit as 40-100 minutes of brisk walking. That’s a different calculation entirely when you’re deciding how to spend limited training time.

VO2max: The Single Strongest Predictor of Longevity

If there’s one biomarker that both Dr. Rhonda Patrick and Dr. Peter Attia agree is king, it’s VO2max — your body’s maximum capacity to use oxygen during exercise.

A landmark 2018 study by Mandsager et al. in JAMA Network Open followed 122,007 patients over 8.4 years and found that cardiorespiratory fitness was the single strongest predictor of all-cause mortality. Not blood pressure. Not cholesterol. Not even smoking status.

The numbers are worth sitting with:

• Elite fitness (top 2.3%): 80% lower mortality risk compared to the least fit group
• Each 1-MET increase in fitness: 13-15% mortality reduction
• No upper limit to benefit was observed — even extreme fitness continued to reduce mortality
• Being unfit carried a greater mortality risk than smoking, diabetes, or coronary artery disease

Here’s the critical link to vigorous exercise: approximately 40% of people performing guideline-level moderate exercise (2.5 hours per week) for several months show no measurable VO2max improvement. However, when these “non-responders” add high-intensity intervals, their VO2max begins improving. This is one of Patrick’s most compelling data points — if you’re only doing easy cardio, you might be in the 40% whose VO2max isn’t budging.

What Counts as “Vigorous”?

Before going further, it’s worth defining what we mean by vigorous exercise:

• Heart rate: 80%+ of your maximum (Zone 4 and above)
• MET value: 6+ METs (metabolic equivalents)
• Talk test: You can only say a few words before needing to breathe
• Feel: Hard to very hard — RPE 7-8 out of 10

For context, brisk walking is about 3.5-4.5 METs (moderate). Running at a moderate pace is 8+ METs (vigorous). Jump rope is 11.7-12.5 METs — one of the highest-intensity activities you can do.

The Key Studies

Beyond the Biswas and Mandsager studies, several other landmark papers shape this picture:

Lee et al. (2022) in Circulation followed 116,221 adults for 30 years. They found the optimal dose was 150-300 minutes per week of vigorous activity (or 300-600 minutes of moderate). Benefits plateaued beyond that range but did not reverse — meaning there’s a ceiling, not a U-curve. Critically, for people already doing over 300 minutes of moderate activity per week, adding vigorous exercise provided no additional mortality benefit. But for those doing less than 300 minutes of moderate activity — which is most of us — adding vigorous exercise significantly lowered mortality.

Stamatakis et al. (2022) in Nature Medicine studied what they called VILPA — Vigorous Intermittent Lifestyle Physical Activity — in 25,241 non-exercisers. They found that just 3-4 minutes of daily vigorous bursts (running for a bus, taking stairs fast, carrying heavy bags) reduced all-cause mortality by 25-30% and cardiovascular mortality by 32-34%. This wasn’t formal exercise — just brief bursts of intense effort woven into daily life.

Howden et al. (2018) in Circulation, from Benjamin Levine’s lab at UT Southwestern, ran a randomized controlled trial with sedentary 50-year-olds. After two years of progressive exercise including two high-intensity interval sessions per week, their hearts functioned like those of 30-35-year-olds — effectively reversing cardiac aging by 20 years. The same protocol in 70-year-olds showed no improvement. The heart appears to retain plasticity only up to about age 60-65. This is one of the most compelling arguments for building vigorous exercise habits now rather than later.

Why Vigorous Exercise Isn’t Just “Faster Moderate”

A common pushback is that vigorous exercise is simply more time-efficient — do less time for the same result. And that’s partly true. When studies control for total energy expenditure, the mortality reductions from vigorous and moderate exercise are roughly similar.

But vigorous exercise also triggers physiological processes that moderate exercise simply does not:

• Fast-twitch fiber recruitment: Type II muscle fibers are preferentially lost with aging and are critical for fall prevention, power, and functional independence. Moderate exercise doesn’t recruit them — you need intensity.
• Greater BDNF production: Brain-derived neurotrophic factor supports neurogenesis and cognitive function. Lactate produced during vigorous work crosses the blood-brain barrier and directly increases BDNF expression.
• Higher vascular shear stress: The increased blood flow from vigorous exercise triggers endothelial nitric oxide production, improving vascular function. There’s even research suggesting elevated shear stress can trigger apoptosis in circulating tumor cells.
• VO2max improvement: As mentioned, 40% of people don’t respond to moderate exercise alone. Vigorous exercise is the primary driver of VO2max gains.
• Cardiac output demands: Vigorous exercise forces greater stroke volume and cardiac adaptation — the mechanism behind Levine’s cardiac aging reversal findings.

The 80/20 Debate: Patrick vs. Attia

If you follow the longevity space, you’ve likely heard of the 80/20 polarized training model — 80% Zone 2, 20% high-intensity. Peter Attia recommends this split, prescribing about 3-4 hours of Zone 2 training and one dedicated VO2max session per week.

Rhonda Patrick argues this ratio is misapplied for most people. Her reasoning: the 80/20 model was designed for endurance athletes training 10-30 hours per week. Even at 20%, an athlete doing 15 hours gets 3 hours of vigorous work. But a recreational exerciser training 4-5 hours per week? At 20%, that’s only 48-60 minutes of vigorous activity — potentially insufficient.

Patrick’s recommendation: the lower your total weekly training volume, the higher the proportion of vigorous work should be. For people exercising 3-5 times per week, she suggests approximately 50% vigorous. For casual exercisers doing 2-3 sessions per week, more than 50%.

The honest truth is that Attia and Patrick agree on everything important — VO2max is king, vigorous exercise is essential, Zone 2 and high-intensity are complementary. The disagreement is about proportions at lower training volumes. For most of us who aren’t training like endurance athletes, Patrick’s higher vigorous ratio probably makes more practical sense.

How My Activities Fit In

This research has given me a new appreciation for the three cardio activities I already do.

Padel

Padel is an intermittent sport — periods of high-intensity effort during rallies interspersed with low-intensity recovery between points. Research on padel intensity shows average heart rates around 74-75% of max, with competitive rallies pushing into Zones 3-4. During a 90-minute match, roughly 30-45 minutes of actual play time is spent at vigorous intensity.

What makes padel especially valuable from a longevity perspective is the combination: cardiovascular training, lateral movement and agility (critical for fall prevention), impact loading (good for bone density), social engagement (itself a longevity factor), and — perhaps most importantly — it’s genuinely fun, which means I actually do it consistently. Adherence is the most important exercise variable.

Running

Running is the most versatile tool I have. At conversational pace, it’s perfect Zone 2 training. With intervals — like the Norwegian 4×4 protocol (four 4-minute efforts at 85-95% max heart rate with 3-minute recoveries) — it becomes the most effective way to improve VO2max.

What I’ve changed since diving into this research is being more deliberate about intensity. Rather than defaulting to “medium effort” runs that are too hard for Zone 2 but too easy for VO2max improvement — the so-called “gray zone” — I now either run easy enough to hold a full conversation, or I do structured intervals where I’m pushing into Zone 4-5.

Jump Rope

Jump rope might be the most underrated cardio tool in existence. At 11.7-12.5 METs, it’s one of the highest-intensity activities available — nearly everything you do with a rope counts as vigorous. Using the Biswas ratios, 10 minutes of jump rope delivers roughly the health equivalent of 40-100 minutes of moderate activity.

It’s also remarkably practical: it takes up no space, requires no commute, and can be done as an “exercise snack” — Patrick’s term for brief vigorous bursts integrated into your day. A couple of minutes of jump rope between meetings hits the VILPA threshold that the Stamatakis study found so effective.

How Much Is Enough? How Much Is Too Much?

Based on the combined evidence, here’s the dose framework:

• Minimum meaningful dose: 15-20 minutes per week of vigorous exercise reduces mortality by about 18-20%. Even 3-4 minutes daily of vigorous bursts (VILPA) reduces mortality by 25-30%.
• Guideline range: 75-150 minutes per week of vigorous activity (or 150-300 of moderate, or a combination).
• Optimal range: 150-300 minutes per week of vigorous activity. Benefits plateau beyond this but do not reverse.

As for too much — for the general population, there is no clear U-curve for mortality. The Lee et al. study found that benefits plateaued beyond 300 minutes per week of vigorous activity but did not increase risk. The one legitimate concern is atrial fibrillation in extreme endurance athletes who accumulate over 1,500-2,000 lifetime hours of sustained intense training — think marathon runners and cyclists doing 10+ hours per week for decades. Intermittent sports like padel and moderate running volumes carry no documented increased AF risk.

Practical Takeaways

Here’s what I’ve changed in my own training based on this research:

1. At least one dedicated VO2max session per week. I use the Norwegian 4×4 protocol during a running session — four 4-minute intervals at 85-95% max heart rate with 3-4 minutes of easy recovery between them.
2. Exercise snacks. A few minutes of jump rope or stair sprints between tasks. The VILPA research shows these tiny doses add up meaningfully.
3. Being intentional about running pace. No more “gray zone” runs. I either go easy enough for Zone 2 (can hold a conversation) or hard enough for VO2max improvement (can barely speak).
4. Counting padel as real training. Competitive matches put me in Zones 3-4 for a significant portion of play time. This is genuine vigorous exercise, not just recreation.
5. Not worrying about an upper limit. At my training volume, I’m nowhere near the risk thresholds. The ceiling is extremely high for someone doing a mix of activities rather than sustained endurance work.

The bottom line is that vigorous exercise isn’t optional for longevity — it’s where many of the unique benefits live. Zone 2 remains important as the aerobic foundation, but if you’re only training 3-5 hours per week, spending half or more of that time at higher intensities is likely the smarter allocation of your limited time.

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.
