I have a large quantity of BOD stuck on Yobit since springtime,  yes.   Every once in a while yobits unlocks it,  but then the units go "transfer from cold storage".   The problem that Yobit has is they are OVER-SUBSCRIBED of BOD coins.  i.e. there are 1 BILLION on yobit,  but if you do a "getinfo" on your BOD wallet.  you'll see there are there are ONLY ~288M BOD on the chain.   at the end of this Yobits has to extinguish the shares they have at a zero $$;  a 100% loss for them.  they know that, and that is why they don't want to open up transfers; as it's all loss for them.  Make sense?
