Good question! The earnings are added to your balances on Betfury in the different coins that you earn. I guess you need to withdraw those manually to your own wallet if you want to get them out. Only the BTC withdrawal requires a quite high transaction, the others can be done to chains (Binance / Tron) which are cheap. For now, I'm just keeping my earnings in my betfury account and I might use them to take some bets the coming football season or just withdraw to reinvest in the future.

I hope that answers it
