I don't know if I agree with that. If it was a casino, it's a rigged casino and you're allowed to bet with the house. If you're putting money you can't afford to lose into coin, well that's a different thing all together.Wrong. You disagree with me, and you want to believe that everybody else agrees with you.
The stock market is a casino, unless you have inside information or an unfair advantage (cf. HFT).
