seriously I don't get it , why if someone deposit and gamble portion of the money in fairlay the don't suspect that the account is shady but if he deposited and not wagered they count it shady
people can deposit and not wager , maybe that account missed the odds he wanted when he got the money
it just doesn't make sense for a btc site to ask for verification IMO , but anyways it's not a big deal if fairlay is doing the verification quick and sending the money right after
I haven't observed what Fairlay does but with other sites, if someone deposits like 1BTC which is substantial and loses half of it and tries to withdraw 0.5BTC. The withdraw will still most likely get flagged and need manual review.
The withdraw amount doesn't matter what matters is where the deposit originates from.
One example is the ETH hack from 2016 which sold some ETC on shape shift and now they might want to mix those BTC.
Since it's all on the blockchain, the casino might be liable for not having any compliance.
