First of all, every trader should believe in his own trading logic. Lossing is not terrible but it needs a lot of patience!!
Here is some advice: 1. Believe in your trading logic./ 2. Record the reason when you open trade./ 3. Take profit and stop loss strictly.
For me, i think as a trader you should learn firstly how to trade, develop and master or master existing trade patterns, methods etc and also learn to tweak your strategy to suit the market demands. Because the crypto currency market is not the same each day. As a trader, you need to understand the market emotions, understand when to trade, understand when not to trade and always take profit.
