Risk vs. reward in crypto: volatility, drawdowns and position sizing
Why crypto swings so far, what a drawdown feels like, and how position sizing, diversification and time horizon keep your risk at a level you can live with.
Every investment balances possible reward against risk. Crypto sits at the high end of both. Understanding what that means in practice, before it happens to your money, is the best protection there is.
Volatility: how much prices swing
Volatility measures how much a price moves around. Large cryptocurrencies have often moved several times more than major stock market indexes, and small tokens move even more. Daily moves of 5–10% are not unusual, and some tokens lose almost all of their value.
Drawdowns: the falls you have to sit through
A drawdown is the fall from a peak to a low. Crypto has gone through several drawdowns of more than 70%. The maths is unkind: after a 50% fall you need a 100% rise just to get back to where you started, and after an 80% fall you need a 400% rise.
Position sizing: the most important decision
How much you put in matters more than what you pick. A small position in a volatile asset can't hurt you much even in a crash, and can still make a difference if it does well. Many investors keep high-risk assets to a small percentage of their total savings and rebalance once or twice a year.
Diversification
Spreading money across different kinds of assets (cash, bonds, shares, property, and perhaps a little crypto) means one bad outcome doesn't sink everything. Owning ten different small tokens isn't really diversification, because they often fall together.
Time horizon
Money you need in the next year or two shouldn't be in something that can halve in a few weeks. The longer you can leave money alone, the more short-term swings you can ride out, though a longer horizon is no guarantee of a profit.
Higher reward always means higher risk
If someone offers high returns with low risk, something is missing from the story. In real markets the two go together. That's why "guaranteed high returns" is the clearest sign of a scam.
Questions to ask before you buy
- How much could I lose, and could I live with it?
- When might I need this money back?
- Why do I expect it to rise? Is that a real reason, or just because it already rose?
- What would make me sell, and what would make me hold?
