Leverage is a liquidation dial, not a profit dial
New traders read leverage as "how much can I make." It's really "how small a move ends me." On isolated margin your position is liquidated after roughly a (1 ÷ leverage) − maintenance margin adverse move. At 10x that's about a 9.5% drop before you're gone; at 25x about 3.5%; at 100x under 1%. A coin that casually wicks 5% intraday will liquidate a 25x position on an ordinary Tuesday — no crash required. The question is never "how much leverage can the exchange give me," it's "how much room do I need so normal volatility doesn't touch my liquidation price."
Work backwards from the move, not forwards from greed
The disciplined way to size leverage is to decide the worst move you must survive first — say a coin swings 8% on a bad day — then pick the highest leverage whose liquidation distance stays comfortably past it. Enter that move above and the result tells you the cap. Anything beyond it isn't "more aggressive," it's volunteering your margin to the next wick. Pros keep liquidation far outside the noise and use a stop-loss placed well inside the liquidation distance, so a losing trade costs a planned slice instead of the whole position plus liquidation fees.
Liquidation isn't the only cost of high leverage
Even when you don't get liquidated, leverage multiplies every fee — they're charged on notional, not margin — and funding compounds while you hold. See what that drains on the fee drag calculator and funding calculator, get the exact liquidation price for a full position on the liquidation calculator, and scan every level at once on the leverage liquidation table.
FAQ
Is this isolated or cross margin? Isolated — the standard, conservative case. Cross margin pulls from your whole balance, pushing liquidation further but risking the entire account; treat this distance as the floor, not the ceiling.
What maintenance margin should I use? Major coins are often ~0.4–0.5% at low leverage and rise at high leverage and large size. Use your exchange's tiered figure for the exact number; the default 0.5% is a reasonable mid estimate.
Does adding margin help? Yes — topping up margin lowers effective leverage and pushes liquidation further away. That's the same thing as choosing lower leverage from the start.
