A friend of my shared that "guaranteed to win" double-your-bet-after-a-loss strategy with me about 30 years ago. The 'catch' is that if you run out of money and can't cover the next bet, you lose everything -- and all you ever win is your original bet (so, a $51,200 win, after 9 straight losses, only nets you $100).

The investing strategy you've presented looks interesting. I've upvoted this post to help generate more engagement.
