That's not an investor, that's a gambler. Gamblers take huge risks and they never know when to stop because they are addicted to the adrenaline (or dopamine) which they can only obtain by making risky bets. That's what you are looking at here. Investors don't take that much risk. They diversify their portfolios in various assets. Most of them are content with pretty conservative returns and that's usually not more than 10-12%/year. When you go above 15%/year it starts to get dangerously risky and it is usually not sustainable when it is above 20%/year.

So turning $3k into $80k was a huge success and he should have left it there. However, we know that he was never gonna do that because that's how he made that $80k in the first place. (by not quitting) If he was a quitter, he would have quit right after he made his 100%. In the end, that's just another gambler's story. From something small to some thing big, from something big to something, from something to nothing. End of the story.
