Does Betfury let you withdraw coins without prior deposits? Or the coins are only free to "play"?
what do you mean by that? i think those coins were only free to play and you won't be able to withdraw those coins? i'm not sure what are you referring to was it bfg token?
He's probably referring to the free sats from the Free Box. Betfury doesn't force you to deposit, unlike other casinos with freebies, as far as I'm aware. Just make sure you meet the minimum withdrawal amount and have enough balance to pay for the fees.
You can also ask in their telegram channel. Support is more active there.
