Crypto is very volatile and one has to be very vigilant. There was a time during covid-19 period when market was so volatile, the market was so scared that orders don't get filled up when people try to closed there positions and in that case, it will be suicidal when you try market trade or sell at current market price because you will definitely be rekt with such move. Volatility plays both side.
