How Much Leverage Should I Use in Crypto?

For almost everyone starting out, the honest answer to how much leverage you should use in crypto is none - and if you insist, two or three times at most. Leverage means the exchange lends you money so your position is bigger than your own cash. It does not improve your trading. It only shortens the distance between you and a forced exit, and that distance is the only thing keeping your account alive.
What actually decides the right number?
Not how confident you feel. Two things: how far price has to move before your idea is wrong, and how much of your account you are willing to lose finding out. If Bitcoin needs room to swing 6% before your trade is genuinely broken, then at 10x you are gone long before that, because a 10x position is wiped out by roughly a 10% move against you - less once fees and funding are counted. The leverage has to leave your stop room to breathe, or the stop is decorative.
Why does sensible leverage feel so boring?
Because it is. Think of it like driving: the speed that gets you home is rarely the speed that feels exciting, and the gap between the two is where accidents live. A trader at 2x on Ethereum looks slow next to someone at 50x posting screenshots - right up until an ordinary Tuesday selloff takes the 50x account to zero and leaves the 2x account with a small, survivable loss. Compounding needs an account that still exists next month.
Is there a number that works for most people?
Start at 1x - no borrowing at all - and simply buy the coin. Once you have kept a written log for a few months and can show that your entries beat coin flips, 2x to 3x is a reasonable step up. Serious traders rarely need more, and the ones who use more are usually sizing from a stop, not from the multiple on the button. The 50x and 100x options exist because exchanges earn fees on turnover, not because anyone needs them.
Before you touch the leverage slider, work out your position size from your stop instead. Decide what the trade may cost in dollars, measure the distance to your stop, and let those two numbers set the size - the multiple then becomes a result, not a decision. Next: how much leverage is too much and how much to risk per trade.
