Investing without confusing conviction and risk
Build a simple method to manage volatility, fees and the size of your positions.
The essentials
Start with the budget, not the chart
First set aside the money you need for expenses, emergencies and upcoming plans. Don't put money you need in the short term into crypto. Then decide on the maximum loss you could bear. "I could make 10x my stake" doesn't tell you what you'll do if you lose 70%, if withdrawals are suspended or if you have to sell tomorrow.
Position size changes the impact of a mistake. If your portfolio is worth €1,000 and one token makes up €500 of it, a 60% drop in that token wipes out €300, or 30% of the portfolio, before even counting other moves and fees. With €50 of exposure to the same token, the same drop costs €30. This example isn't an allocation recommendation: it shows why the amount invested matters as much as conviction.
Before buying: five questions
- What does the asset do? What real demand, rights or functions does the token have?
- Where do the numbers come from? Check the circulating supply, future supply, unlocks, liquidity and the difference between market cap and fully diluted valuation.
- How do you get out? On which market, with what volume, what depth and what fees can you sell?
- What could break the thesis? Product failure, competition, a hack, the team, regulation, dilution or the overall market.
- What size and for how long? Write down in advance the amount committed, the time horizon and the conditions that would make you reconsider.
Past gains don't guarantee future gains. A small market cap can offer upside, but also thin liquidity and a risk of manipulation. Yields advertised in DeFi add risks that aren't captured by the promised percentage.
DCA, diversification and a journal
Buying a fixed amount at regular intervals, often called DCA, can reduce the temptation to guess every top and bottom. It guarantees neither a profit nor a better price. Diversifying can keep a single asset from dominating your results, provided you understand the shared risks: ten tokens from the same sector can fall together. Keep a simple journal with the date, the reason for buying, fees, quantity, price and reasons for selling. Review your thesis periodically, without changing the rules because of a single price candle.
Shortcuts to avoid
Leverage can liquidate a position before your long-term idea has time to play out. Borrowing to buy also amplifies losses. An influencer, a private group or an affiliate link may have its own interests: look for primary data and the exact terms. Finally, the "price per coin" alone says nothing about whether a project is cheap; look at the supply and the valuation.
