y happy to see a comment from Bountyhunters team because I like your service and used it on daily basis.
I don't see any other option to withdraw this tokens only with private keys share.
Due to technical reasons the complete update will be released today.
Note, that it is not necessary to transfer your tokens to the wallet. When we implement the buyback widget (1st quarter of 2019), you will have an option to sell tokens right from your profile. You can transfer your tokens only in a case you want to sell it on the exchange (the listing starts in December).
If you are ok with our answers, could you please translate them in the other thread you created? (
