Sportsbet.io don't charge for withdrawal fee if you deposit. It's because you were given free bets, that's why there was a wager requirement.
I edited the post, I made a mistake. It is not withdraw fee but minimum withdrawal.
Free bet is for fun and not to make profits which is the reason why you cannotmmeet up with their wager requirements.
I did not post that free bet is for making profit.
Also generally betting and gambling should be for fun and entertainment and not means of making profit.
It is worth knowing that I have won the bet several times, got yo to the minimum withdrawal and I withdrew money on the gambling site. K still have one free bet waiting there also, probably if it has not expired.
