I think this topic must be moved on Gambling Discussion IMO.
snip-
In your opinion which of the gambling sites give the highest return on investment.
For me, I never look the highest return(ROI)on investment in gambling site. I'd rather choose reputed and legit gambling site, because for me if gambling site gives high ROI I think they are a shitty gambling site. But this is a case to case basis depending on the gambling site you're planning to invest.
I found this link thread offering to have crypto game investment.
