i dont know how much you deposited but lets say you deposit 1000usd then you want to withdraw it without wager
doesnt that  trigger a question on why you deposit at first place you think its a wallet ?

actuallyi dont like roobet as i see a lot of users has troubles with them but i think you behavior is strange too to deposit there and not to wager
even stake also require that on my experience with stake use a wallet if you do not want to play
