Welcome to the forum, Betkin.

I've check your X account, it's quite sad to see your casino almost has no traffic in X even though you were active. Some casinos become big from X, some casinos become big from this forum, so I hope promoting in this forum will make people aware with your casino.

I hope it's real zero, which mean the casino cover the transaction fees paid to the miners.

Not "zero" where the gamblers still need to pay transaction fees, but the casino didn't take extra charge.
