Liquidation is something I fear the most in my trading history, because no matter how sure you are about a trade, the market can decide to go otherwise. If you've only set a take-profit (TP) without setting a stop-loss (SL), you'll surely face liquidation at the end of the day.
This means you have been trading just altcoins is what I am thinking and that you are not trading bitcoin. Or you are using a very high leverage if it is bitcoin that you are trading. High leverage is not necessary for altcoins to liquidate you because thet can go 2x at anytime. Just gamble with them those highly volatile altcoins.
