yep),a bit of negative to your bright conversation.. as for me the main problem in online gambling is not the payment source or other possibilities that btc can give ,but irresponsible and even scam gambling sites owners and as of now any online gaming licence can't really give you protection (MGA, Currocao etc). Maybe its more about bookies and poker rooms then casino, but still..
Yes with the introduction of bitcoins in gambling, where it is very easy for the gamblers to play gamble , on the dark side is that many sites of gambling has come up whom sole purpose is to scam people like taking the bitcoins and never give the withdrawals OR making backend codes with fake house edges etc.
this has been increasing a lot recently people are taking the advantage of the popularity of bitcoin if you see most of the legit sites are in profit so why does the site even want to scam it's users if it get's more trust it is better for them they can earn more profit instead of scamming users
