Greed has altered the course of life many times over.
I continually fight this myself. I made a fair amount of profit in crypto, but I 100 percent realize that it's just blind luck. I like the idea of it and I love the news about it, so it's very difficult for me to not to go 100 percent in every time I see a trend!
So far, I've resisted the urge to go to crazy with it, but ugh, it's tough . And I lie to my gf and tell her that I just follow, but don't invest. So I'm pretty much the kind of asshole that I grew up despising. lol
I've never invested more than I can afford to lose, and cash out the minute I make a little profit. But I can see how addicting it is and how easily some people could fall off the cliff.
