Hello! I dont know. Only you can make a decision! I also have a lot of coins for which the price has fallen. But I will not sell these coins! I think the price for them will grow!
I agree with you about the fact that all decisions must be made by yourself. Of course you can listen to people who give advice, but that does not mean that you need to act on it and before you need to have a strategy.
If you will listen people who tell you waht to do you will never become a real investor. You should de reserch by your own!
