If there's a way to always win in gambling, I also doubt that someone will share it or sell it for just a small amount of money.
Agreed. Even if this was true, hypothetically, it doesn’t really make sense for someone who found the trick to have guaranteed winning to even share it anyone. This scam scheme is so ancient, and I hope no one would ever fall or even entertain the idea of believing this. Because if someone did, it is a case of ignorance and gullibility, since this has been talked about many times.
