Investing in casinos will give you more profit than Bank. The banks will give very less percentage of your investment, but it is safe. You can trust them, and you can invest for a long time. But investing on casinos is not good for the long term we can not predict the site performance for the long term. But if you keep on watching your investments and you know when to withdraw your investment you can try casino investment.
Obviously depositing your money in banks cannot give you a good profit in form of interest. While investment in bitcoin or trading altcoins can give you a good profit. But investment and trading is also more risky compared to simply saving in banks.
But I feel investing into casino might get you better benefits than banks but lesser than trading. But risk levels is depending on how hard you research and choose a casino.
