The only way to stop losses in Trading.
1. Never trade entire capital. I advice you to start always trade with only 10% of the 100% capital.
2. Remember that in crypto its very common that Ups and downs.. It will suddenly goes 40%-50% up and suddenly dip to 60% down. This thing, no one can predicts it.
3. Leverage: Try to avoid this thing completely if you are not able to use stop loss. No one can trade 100% win trade in leverage trading.
4. Never trade shitty coins.
