Becoming a real investor

DCA = Dollar Cost Averaging. Principle: you decide on a fixed amount (e.g. €50/month) and invest it automatically each month, regardless of price.

When prices are low, you buy more crypto. When high, less. Over time you get an average price — not the worst, not the best. Emotional stress disappears.

Let's imagine: you decide to invest €50 in Bitcoin on the 1st of every month, for 12 months. Over that year, the price of Bitcoin swings between €50,000 and €80,000. No need to think about it: every month, you buy €50 worth.

By the end of the year, you've invested €600 in total. You've accumulated Bitcoin at different prices, more some months, less others. Your average entry price will be somewhere in the middle — shielded from the extremes. If you had put in €600 all at once at the wrong moment, you could have lost 25% the following month. With DCA, that risk is spread out.

Lump sum (investing everything at once) statistically beats DCA in roughly 2 out of 3 cases, because markets rise more often than they fall. So the longer you wait to invest, the more upside you miss on average.

But 'statistically superior' isn't the only measure. DCA wins on emotional stress. And in the event of a sudden drop right after your purchase, lump sum is psychologically devastating (you might give up). DCA, on the other hand, keeps you invested over time. That's why it remains the recommendation for 90% of beginners.

HODL ('Hold On for Dear Life') is the long-term investor's mantra. You buy (ideally via DCA), and hold for years without panicking during dips.

The numbers speak: 95% of people who bought Bitcoin and held for at least 4 years are in profit, regardless of their entry date.

A real investor isn't chasing the genius move. They apply a few simple rules, without emotion, and let time do the work. It's the opposite of the trader who watches charts all day long — something even professionals rarely pull off.

Passive management over active management: statistically, regularly buying solid, established projects and holding them beats the vast majority of people who try to buy and sell at the right moment. The less you touch, the better.

Deblock lets you set up recurring purchases in a few clicks: you pick the crypto (Bitcoin, Ethereum…), the amount in euros, the frequency (weekly, monthly), and the debit date. You can pause or change it at any time.

Recommendation: start small. €20, €30, €50 a month. You can always increase later once you feel more comfortable. What matters is staying the course over time, not putting in a large sum all at once.

Backtesting means applying an investment strategy to historical data to see what it would have produced. It's not magic — past performance doesn't guarantee future results — but it's the best tool to understand how a strategy behaves under stress.

Applied to DCA, it lets you answer concrete questions: what would a monthly €100 investment in Bitcoin since 2020 have returned? What if I had started just before the 2022 crash? Numbers replace intuitions.

Comparing BTC, ETH, SOL, the MSCI World ETF, and no investment (0%) over 2 to 5-year windows, one constant emerges: duration almost always beats timing. Even starting right before a crash, a DCA lasting 3+ years in crypto or global equities tends to finish positive.

The worst enemy isn't bad timing — it's money left on the sidelines.

The data is unambiguous: waiting for the 'right moment' is costly. A study of 20 years of equity markets shows that missing the 10 best days cuts returns in half. In crypto, the effect is even more pronounced.

DCA solves this by investing automatically — you can't miss the best days if you're already in the market.
