With the bitcoin transaction getting slower by the time, i don't think that bitcoin gambaling will live on, at least some of the gambling sites, i mean i used to play some sports gmabling on one of the best gambling sites wich was DirectBet, i used to put my bet and send my coins and instantly gets confirmed bu as the transaction got slower and the fees getting higher som any people were not able to do this anymore so the site shut down, the core element that diffenciates bitcoin gambling from real money gambling which is faster transactions was removed so you would be saving yourself a lot of money if you go to a real casino and use real money rather than jut wasting bitcoin that you could save and earn a lot from it.
