The argument itself is valid. Way back 5 years ago, online gambling is running through fiat digital currencies and by far experiencing it before, I would say that transaction fees are a bit expensive and sometimes, delays do occur. I am not familiar with when did online gambling industry exactly adapted block chain technology but surely, such technology is dominating the industry itself. Gambling sites which are crypto based, dominates the world of online gambling. The population of gambling sites are continuously increasing at this moment and most of them are block chain based. More people are being able to play despite of restrictions since block chain technology secures their anonymity. Transactions with regards to deposits and withdrawals are smoother in a way that it costs less yet faster in all aspects. This makes it not surprising why many people are now getting hooked up into online gambling than in the actual. It seems to be the new era of online gambling, and surely, sheds a bright future for gamblers and to the industry as well especially once cryptos are accepted to most of the countries.
