Stop losses are a good feature to protect your investment, although you need to be careful at what levels you set them & be happy with the risk that a sudden quick spike downards could stop you out before price pumps again. There's certainly money to be made in trading in a bear market, but that should be left to the pro traders. For the majority of us, it is better to either just hold fiat & wait on the sidelines until evidence of a bull market cycle starting, or just hold your crypto & ignore the day to day prices for the time being.
