Eli5: Why can’t you just double your losses every time you gamble on a thing with roughly 50% chance to make a profit

399 views

This is probably really stupid but why cant I bet 100 on a close sports game game for example and if I lose bet 200 on the next one, it’s 50/50 so eventually I’ll win and make a profit

How many bets can you afford to lose in a row? In a losing streak, your bets would go like this:
100
200
400
800
1600
3200
6400
12800
25600
51200
102400

That’s just each individual bet. Keep in mind that you have to add each one up to know how much you’ve already lost. So, for example, at the $6,400 bet, you’re actually in for $12,700.

And when you win, your profit is just whatever your original bet was. Say you’re unlucky and get all the way to the $102,400 bet. But then you win. Overall you’re only up $100.

And when you have a winning streak? You’re still only getting $100 profit per win.

Edit: just go try it on any free version of a game like roulette. Bet red every time, and double your bet whenever you lose. Give yourself a bunch of money and start with the smallest bet. You’ll see how it tends to play out.
