Everyone who conducts crypto trading must already have principles and know about profit or loss. My principle is that I will never sell when I see the results will lose, I better hold when the coins that I have bought are decreasing in price (holding is not afraid of losses) but part of the strategy. And I will sell when I increase, although I will definitely sell a little. Never be afraid to experience a loss, because loss is one of the risks in trading. But you must have a strategy.
in my opinion thats called HODL mate, not trading
because a trading activity is always have a profit target and stop loss level
stop loss level is more important if we comparing with profit target, why ? because we should reduce our lost, with stop loss level we cut our losses in short
