The biggest mistake anyone can do is still holding unto their altcoins when bitcoin touched 60k weeks ago and still holding strong when the fall began weeks ago, imagine someone still holding HEX token when the coin did 40x already? If you are someone like this friend I don't know what your aim is but sorry to say you are doing it wrong. Check yourself cos it's possible you are struggling with greed.
I am sure 80 % of people here tasted both sides of this issue. Either you hold for too long and miss the top and then too proud to sell, or sell too early and watch price rising with tears in your eyes.
There is no way around it and it will happen to all of us sooner or later.
