Increased a lot,even I started to play gambling with much money since I am playing at the crypto gambling sites but before I just used to play very small amounts at fiat based gambling sites.
Its because of the advantages crypto gives over the traditional gambling money method. Even if you think about the land based casinos you would have to use fiat to pay for the chips there and law enforcement would definitely be keeping track of you. If you want to escape them and still try to double your coins you would obviously go after some method that does not allow tracking.
Without any doubt crypto has changed the way the online gambling industry run nowadays and in future this will generate the demand for coins and drive the market.
