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.
what do you mean casino site only get return 1-3%/year
all online investment include gambling site or casino site is return is big, if gambling site or casino site return is proportional from gambling site profit
another gambling site minimum 10%/monthly, in cloud mining majority BEP over 1 year, or equal over 5%/month
so if you write only 1-3%/year is very low profit, nothing people interest and join to invest
No, you are not understand how investment works. Even though you are invested your money in some reputable gambling sites which offer investment option, doesn't mean you can always profited from that. If you are not lucky, your investment amount will decrease or loss because you are shared with profit/loss from that gambling site.
There is no guarantee when you invested in gambling site you will earn minimum 10%/monthly. Show me the proof which gambling site will always give you min 10% profit monthly, could you?
