What i mean is that, if i win 300$ worth of cryptos from 1xbit, do you mean they are not going to pay it to me? I think they would.
No, they most probably won't pay you those $300 that you win and they may also not allow you to withdraw your own deposit. Everyone on this forum warns newbies to stay away from 1xBit, the reason for that is the shady nature of that casino.
They don't care that if someone wins $300, $3k, or $20k, they are shady and they can show their shadiness with even $100 worth of funds. Be careful from them even with small amounts because if you trust them then you'll regret later.
