What is the purpose of this thread? You're literally just stating the complete obvious.
I don't think I've ever seen a casino market itself in such a way, most are actually pretty transparent about their house edge and provide advice on how to combat gambling addiction.
It's all a mix of risk vs reward, sure you can double your money at most casinos, but the odds are slightly more likely that you'll actually lose your input instead.
The purpose of this thread is to trigger people who will say "what is the purpose of this thread"
And you're dead wrong about the transparency.
