Well for me I would not invest on casino sites. Before you invest do all of you research first on which one is legit and all the information about the site thats because many websites now are scams especially if you are risking your money/BTC. Investing is very risky but if you did your research right and not just investing on just random sites you either will lose your money/BTC or just nothing will happen on your investment and also whenever you are investing don't just stay with just one website. Don't just dump your money in once place it would be safer if you invest in other places for you to earn more.
