Im done trading crypto(please help)

Im trading crypto (with leverage) and specially alt-coins for a good 3 years now. Losses are still more than the wins,but i just keep coming back because i find the volatility intriguing and exciting(also profitable if you are lucky). I tried everything,all the indicators,all types of candles and strategies on the charts,but eventually,my biggest enemy,is my own self(my feelings). I rush to close a winning trade and i stay too long on a losing one. Also i hate using stop-loss in crypto(i still do tho),because 90% they gonna hunt for your stop and then the trade will continue your way(once they flushed you out ofc). After 3 years in this nightmare,i try to keep simple and i only use support/resistances,Rsi and sometimes Macd and moving averages(but only to spot if something is oversold/overbought). My question to you guys is: What else can i try and study/learn? I know everyones have different strategy and trade on different timeframes,but have you found anything that “really” works for you? I usually trade 15m charts for a quick swing or 4h if i wanna keep my trade open for a day or two. Should i learn how to “read” candles? Does it even work with crypto? Should i buy “market cipher” indicator? Should i just leave crypto and go for something “less volatile”? I feel like no matter how good of a trader you are,Bitcoin is so over-manipulated,that it can ruin your trade within a blink of an eye,just with a nasty move. What did actually work for you guys and what are you trading with most success? Thanks for your time and stay safe,good luck 🙏
