That's a good idea but most of the trusted casinos out there provide really less returns like 1-3% a year as far as I have heard. It may be more but unfortunately it is still less than the return bitcoin provides you every year.
So I would recommend you to not invest in any caaino and let the bitcoin stay in your wallet.
1-3% in a year? where did you heard that? that return is when you deposited your money in bank. I've said if my investment increased 20% since i invested my money in a dice site (if you read my history post, you will know where i invested) on 6 months ago. The return could be more if someone lost a lot or it could decreased when someone won a lot.
That was a investment return which is guaranteed and no risk it is kind if like bank. I also agree that gambling sites provide really good returns but lately I'm bit scared to invest in them because of scams. I have tried yolodice from yesterday and leverage 1 let's see if it's profitable after a month or not.
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.
There are ways to manage risk and therefore investing in casinos are very attractive, it will give us a consistent income as they consistently win all the time. Now, if an investor does not want to take that kind of risk, he is free do it with banks and get a little return of his money.
As for me, I need to take bigger risk as my money is not fit for low risk investment since I believe I will not grow it in a good amount in time.
