YoBit has to-date completely ignored our attempts to get them to upgrade their wallet. (It appears they may only do this for an outrageous fee.) So we did our best to inform everyone to withdraw their BITS from YoBit before the hard fork/wallet upgrade. At this point, "BitStar" on YoBit is still running an old fork, which will no longer be supported (the fork was necessary to do all the new features being worked on - see roadmap) and is incompatible with the current wallet and Cryptopia (who has upgraded). In retrospect it would have been wiser to never have worked to get listed on YoBit in the first place.
