I follow some rules. Am not sure if they will work you for everyone but these are the basics.
1. Keep it simple. Once I tried to gather as much info before start trading. Many indicators, many news, vast analysis made me paralyzed to trade.
2. Avoid crypto trading on weekend and Friday too. Instead enjoy the holidays.
3. Never do Revenge trading, you will only trade whenever you have proper mindset.
4. Never love any asset, emotional trading will kill your investment.
Consider those tips as free gift, not financial advice. Always do your own research
^ These are simple advises but the fact is very meaningful. In trading, you should know about the basics before digging into difficulties just like technical analysis. That is also right that doesn't spend too much on trading or doesn't focus too much. Too much emotion will let you down in trading and probably make loses. That's why there is self-control and we should know which point we limit our selves in trading. Nevertheless. holding is the best option than trading.IMO
