The best would be a direct payout at a wallet (segwit).
I can understand why the campaign owner favours a payout into the account. But we users are also taking a number of risks and if I see it correctly, this is the only campaign at the moment that does not pay out direct to a wallet.
Direct payouts would be better, yes, but we don't have a problem with payouts received in our gambling wallets as long as we are not charged such high fees when we withdraw our funds. Those who wish to keep their funds on the platform and gamble with it should do that, but those of us who wish to withdraw the funds and use them for some other purpose should be allowed to do that without having to pay any fee or at least not as much as 7-8% of the total payment.
