What About Crypto?
Crypto is different from everything else in this guide. When you buy cryptocurrency, you're not buying a piece of a company. You're buying digital assets — a completely new type of money and technology.
What makes crypto different?
Cryptocurrencies are decentralized. That means no government controls them, no bank manages them, and no company can shut them down. They run on blockchain technology — a public, transparent record of every transaction that anyone can verify.
Unlike stock markets that close on weekends, crypto markets are open 24/7. You can buy, sell, or send crypto at 3 AM on a Sunday if you want to.
Two cryptocurrencies have proven themselves
There are thousands of cryptocurrencies out there. Most of them are worthless. But two have stood the test of time: Bitcoin and Ethereum.
Both have been around for over a decade. Both have survived multiple crashes — some devastating — and come back stronger every time. And both are now part of mainstream investing, with ETFs approved in the US and Europe.
The risk/reward spectrum
Everything in this guide so far has been about ETFs — steady, reliable, proven over decades. Crypto is the opposite end of the spectrum: volatile, unpredictable, but with returns that dwarf everything else.
Here's what happens if you invest €250 per month for 20 years at different historical return rates:
| Investment | Money invested | 20-year value |
|---|---|---|
| ACWI ETF (~8%) | €60,000 | ~€147,000 |
| S&P 500 (~12%) | €60,000 | ~€230,000 |
| Nasdaq (~15%) | €60,000 | ~€360,000 |
| Bitcoin (~30%) | €60,000 | ~€1,300,000 |
| Ethereum (~40%) | €60,000 | ~€3,500,000 |
The difference is staggering. But so is the ride — crypto can drop 50–80% in a bad year. You need serious conviction and a strong stomach to hold through that.
How to think about it
- ETFs are the foundation — steady, reliable, proven
- Crypto is the optional turbo boost — high risk, high reward
If you're brand new to investing, start with ETFs first. Get comfortable with the process. Learn what it feels like to watch your money go up and down. You can always add crypto later.
Once you're comfortable, even a small allocation — say 5–15% of your portfolio — can significantly boost your long-term returns.
Key takeaway
Crypto is high-risk, high-reward. ETFs are the foundation — crypto is the optional turbo boost. The next two chapters cover the two proven winners: Bitcoin and Ethereum.
