So here is the things which we should do in trading,
1. Monitor the bearish and bullish market carefully
2. Follow the trends going around the crypto world
3. Invest only that amount which we can bear to loss.
And the following things we should avoid
1. Greed while trading
2. Keep the emotions away from trading
3. Don't invest in dump coins
This is my experience which i write with clear words and what your experience and addition in this post.
The experiences of successful traders books I read are more detailed than yours. and after reading it I didn't apply much because every year the market was different and it didn't really suit the volatile market like crypto. It's best to experiment with small capital and only make big bets when we know some of the market trick. For example, for the crypto market, I realize our stop loss must be higher and should only use indicators instead of the price action method.
