Based on the other thread it is said that those casinos which are regulated doesn't need to require KYCs for this. They will continue to do the same except for the new thing which is proving themselves within having a loss of $100 or maybe £100. I don't think it would be that big for them to gamble underground.
I think they have to require KYC during the registration if the £100 monthly losses gets implemented because casinos can't just guess or assume which of their gamblers aren't capable of handling the losses. Anyway even if it's approved this won't be a problem to most of us crypto gamblers since it's only from the UK while most crypto casinos are regulated by Curacao.
If the regulations are implemented in the UK, I think the other countries will not get the effect, and the gamblers can still playing gambling, even they will get losses more than $100. I think the gamblers don't have to prove themselves of having a loss of $100 because I think for some gamblers, that will be an embarrassing thing for them because they told other people or government about their losses. I guess that crypto gambling will not be a problem because we can select the gambling website, which doesn't require KYC to play gambling.
If the results are good in the UK you can bet they will implement it elsewhere. It's not that bad, especially when considering that if the gambler loses a lot the government will have to give them social benefits.
