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
I like the first three points, they seem wise and helpful. They are oriented towards limiting trading in such a way that it becomes simple, leaves time for other things and prevents affective decisions. I think that there should definitely be the golden trading rules of never spending more that one can afford to lose and buying low, selling high in this list, though. And since it's a forum, mainly dedicated to Bitcoin, it pains me to see #4. Maybe it's because Bitcoin is just not supposed to be traded, but I think that people dealing with Bitcoin should have a personal connection with it, believing in it and worrying about it. Otherwise, they disrespect a great innovation and use it as if it were some useless asset on the market.
