Crypto tip: Isolated vs. cross margin
In cross-margin mode, the liquidation price is usually farther from the current price, but if you do get liquidated, you could lose your entire account balance.
In isolated-margin mode, each position only uses the margin allocated to it, so if it gets liquidated, the most you can lose is that margin.
Don't laugh—I learned this the hard way too.
