So no one should be worried about casinos somehow getting the same treatment as other websites that could facilitate those practices.
This is the simple answer to that, the government, or the AMLC is trying to implement a KYC and those who don't follow will be considered as illegal.
Casino - Followed KYC (yes it's legal)
Mixer - NO KYC ( it's illegal)
That's how they see it, so casinos are on the safer side while Mixers aren't. It doesn't matter what our purpose in using a mixer but the government sees it like an illegal activities, so they'll ban it's use.
I don't think have place for crypto casino become place for money laundering because many of gambling platform required with KYC and difference with Mixer they are free and not allowed KYC for every time mixing bitcoin transaction. Although have little space left with crypto casino become place for money laundering but difficult for withdrawing huge amount if not pass KYC.
Some platform of crypto casino have allowed with government rule ask KYC for their user and I think not problem with many illegal activities in gambling crypto casino platform. Less with crypto casino have seized by government like Mixer of bitcoin have blocked some mixer platform until right now.
