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.
HEX is a token that has skyrocketed this year, I think if you have a large amount then I recommend selling even in small portions, holding is a good technique because it is easier than daily trading.
