Anonymity and popularity of Cryptocurrency are two of it's the best attraction.
And Cryptocurrency games are more transparent.
Will, there comes a time that all online gambling sites will be Cryptocurrency based?
Crypto-based gambling sites are still behind in the competition. Sites like Bet365 have over 35 million users whereas biggest of the crypto-based gambling sites have at max like 1M users.
But the thing is crypto gambling is much more anonymous and non-traceable. These features surely attracting more and more people towards crypto gambling. The only condition when all online gambling sites start using cryptocurrency is when users demand for that.
Consumer is the king! As far as users are ok with fiat gambling, I don't see any reason why sites like Bet365 will switch to crypto.
True, but the time will come when people will appreciate a lot more the characteristics of cryptocurrencies, now most people do not understand why it is a good idea to have a currency that governments cannot print at will since they see the economy still working, but there are indications that show that the economies of the world could face huge problems during the next decades, and if they do, you will see many people pushing for the adoption of cryptocurrencies not only in casinos but in all kind of businesses.
