Where it sits
The more leverage, the closer the liquidation price is to your entry. A position is liquidated when the coin moves against you by one divided by your leverage, less a 1% margin kept back. Drag the leverage to see it move:
entryliquidation −9%
1x25x50x
2x49%
5x19%
10x9%
20x4%
50x1%
Small coins move fast
A coin at a 5k market cap can move 20% in a minute. At high leverage that is enough to liquidate a position before you look back at the screen. Lower leverage gives a small coin room to move.
What you can lose
Never more than the collateral you put in. A liquidation takes the collateral and nothing else.
