Many people don't understand the very simple reality of finance, wealth appears to evaporate overnight when in reality nothing of the sort really has happened. When stock or crypto go up in value wealth is created out of nowhere by that thinking, but really isn't. For those of us who are seasoned investors we know better, but writers can get more attention pointing to doom and gloom than the explain the reality.
I agree, always take profits, and you can always buy back in with them if you want to if the time is right. Or not... But you're right, in the end the house always wins just like banks always make money!
