If this is first time you are using stop loss in crypto market, make sure you know where to put the stop loss. Crypto markets are very volatile and exchanges hunt for your stop losses. I usually put the stop loss in my mind specially in the futures market. How many times i have see that prices dump and wicks are made only to eat your stop losses and then the prices move back up.
You mean that you will keep your stop-loss levels in mind and when prices are coming down then you will exit your positions? I remember MT4 or MT5 platform is having a feature like hidden stop-loss which will make exchanges unable to watch for your orders but not sure how effective still you may have peace of mind and you can go for stop-loss order well in advance.
