This is just my thought:
1. Never stop learning about in trading
2. Be patience
3. Don't be emotional
4. Don't be greedy
5. Be positive
6. Have self-discipline
7. always watch youtube tutorial about in crypto trading.
i think most traders know they should follow these advice but its easier said than done, you cant tell someone who is down 90% of his initial investment to be positive, and also patience is something thats very hard to do.
