5. Buy the rumors and sell the news!
6. Don't buy at an all time high.
7. Don't do pump and dumps.
8. Never sell in loss (depends on stop loss of course)
9. You try to get more bitcoin in the long term.
10. Sometimes the market plays against you, skip the day.
Never try to being a greedy person, this is why so many newcomers are being trapped by the market. I have been doing all of the things that you have been mentioned in your thread. So far i never had any problem with it.
TA and FA will help you a lot in this case. never try to forget it.
greed is the nature of every human being and when we get profit, there is greed there to function and our heart will fight between satisfaction and ambition. if we lose we will be trapped by ambition and greed to get more profit, lucky if we get and what often happens is loss. man is never satisfied with his achievement.
