We have already seen this transition and it is really that gradually happening now and as we have seen that those known KYC-less platforms back in the past are now leading on imposing up such rule about KYC verification before they could be able to sign up (Roobet) and able to make withdrawals (Stake) on which its something that you do need to comply before you could proceed. At first, whom had thought that these sites will really be that becoming strict when it comes to compliance?. Some people had already anticipated it on which same as you said that government wouldnt really be allowing for these businesses not to be regulated or something that they cant be able to milk it out with some taxes.Therefore, they will really be trying out to control these businesses and will really be requiring out to follow up some regulation for them to continue on operation on which these businesses wont really be having any option but to follow or else they will really be facing up some problems.
It all depends on what jurisdiction a particular gambling site is in. Those gambling sites you have mentioned most likely feel fine in their current jurisdictions, and they just follow the requirements of the regulators. However, I think that any major gambling sites can easily change jurisdictions if the regulators, for some reason, put a lot of pressure on them both in terms of restrictions and financial.
