How to control over trading ?

Whenever I think about my startup crypto trade journey, I feel aww that how emotional I was attached with my trades,and how much losses I bear..my first investment became zero even I close trades in profits too, After strong analysis I opted out some strategies and regain again. Some of them are :

1: In crypto trading there are some Do's and Don't s....stick to them strictly

2: Don't throw your full investment in single trade .

3: Always follow the percentage formula for investment...go for total 5%investment of full investment

4: Further remain half percentage out of this 5% for 2nd entry for safe side...

5: Never blindly estimate any crypto.....go for proper techniques and technical analysis.....
