I’ve been studying and playing for about a year now, but no matter what I try, I end up losing over time. People say the game can be made profitable, but to be honest, it’s starting to feel like that’s just a myth.

Hello, I don't think it would be possible, maybe if you knew how to count cards. That's the only "strategy" I can think of to beat blackjack. If someone is just playing it then it's just luck. 

But we have a guide to it, if you read it, you might find something useful to try. 

Have you seen it yet? ??
