I agree with Brainboss although I find a stop loss of -10% quite low when trading cryptos due to the high volatility. I use a stop loss of -25%.
Now after recording some profit, you should constantly readjust your stop loss to be in profits incase of scenario when the market declines. I used 10% because that's my limit but you can constantly increase yours to 10,20... percentages until youre comfortable with the profit you have gotten. In summary, turn your stop-loss to take-profit
In fact, than you put in a trailing stop opder. Taking a profit is always a good idea also.

10% of market price or 10% of investment ( i use 1:10 leverage)
