Of course they wont really be making out such terms and conditions yet players would definitely be flocking away and avoiding this site as much as possible.Who would really be the one to like on dealing up on a gambling site on who doesn't have that instant withdrawal? or something that do talks about having no capacity on paying up such big wins? You would be totally be avoiding this place in the first place.
About on that player then its "efialtis" which is a known member of this forum specially he's the one who had made out that BTCGOSU which is known to be review site. Good thing that they had made out such review and feedbacks in relation to this on which it do really be able to save up other potential players of this forum on experience on the same problem.
Really totally frustrating on the time that you are really that needing to wait for too long until you could really get your winnings or able to withdraw. Just like on what @Oilacris said above
that it is really just a reasoning and its an obvious one that they are really just avoiding to pay up that big win or simply doesn't have the money on doing so.
If they indeed concealed the truth from the players and haven't started such withdrawal limits in their terms and operation that gamblers need to read and accept before creating an account, it then means that the casinos have committed clear cases of abuse of the player's rights, this is because at some point the gambler can really build a case against the casino, and having such wired condition as for gamblers having to wait out a number of days between withdrawal when the balance reaches a significant amount that is above the deposit.
This law is very wrong and we should not encourage it in any way since gambling should be for fun and crypto is all about freedom without possible financial limitations.
