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.
Smart investors always take profits, only fools see their investment amount turn into 40x and do not take profits, what else do they expect? 1000x or more? or 10000x as we see greed is the problem of many people, must learn to stop being greedy and take profits when they reach their desired number.
