So the problem is that soon there will be no exchanges without KYC and users will have to pass KYC on all exchanges. The same goes for the casino. Only very small exchanges and casinos with low liquidity or outright scammers will leave.
But new services keep popping up every day, and they seem to know what crypto users like which is privacy or anonymity so that time may never come. If it was a case where there were no new services being opened, then today we wouldn't have any new exchanges or casinos with relaxed KYC verifications.
