my question to you is: have you ever tried any of these strategies before? were you successful?
"they usually involve increasing the bet after a loss", Do you mean the martingale strategy? yeah, I've tried it, and it didn't work, but theoretically it is a "win-win" strategy, but then again it only works on infinite funds and no max bet amount which you or any gambler has and casinos usually have a max bet amount. so yeah, while it is a "win-win" strategy theoretically, it doesn't work practically.
