Why not, try to exchange a small amount in yobit first if it works then exchange the remaining amount but if not, better to hold that token and wait for new exchanges to sell it.
Well, if you read what i post.
@OP cant sell & withdrawl the token cause the wallet & price token, to be honest he only can hold until the wallet back online again if he really luck the wallet online again. Make an order with more than 4000 bitcoin estimation order was really impossible he need to wait 400 years with 0.1 volume transaction trading.
