In my opinion, the best time to sell is when the market price of the coin is 20%+ higher than the market price at which you bought the coin. Dont wait till the market price is 95%+ before you sell. That only happens when you got your eyes glues to your machine 24/7. Dont be greedy... Make a little profit and grow it over time. Cryptomarket is growing and full of terror! Be careful
Is not necessary that one should even wait until the price grow to the level of 20 percent and above before one should sell, but advising people to sell when they hit their target point which some times could even be less than that of the 20 percent profit as you rightly mentioned above. And I want advise people not to set high target except you want to hold a long time period.
Well, high goals are also a part of showing the greed of traders, and this is really not an incentive because if we are not satisfied with the relative profit levels, we may regret it in the near future but a sad fact is that many traders do not accept a too low and relative profit level, they always ask too high for profit, set high goals, miss a lot of opportunities. The profit is small but stable and safe while the profit is high but unstable and risky, a very understandable lesson for traders but very few people can learn, profit has made us ignore the basics
