I just got the official word from Poloniex.  They are going to de-list BTM.  They are frustrated with the downturn in volume and they have decided to invest their resources into other coins instead of trying to fix the broken BTM wallet.  If you check Coinmarketcap, you can see the BTM volume has gone way down in the last few days.  Novaexchange will be the only exchange that has BTM when the coming Poloniex de-listing occurs.  It is currently trading at about 2400 sats on Nova, with no upward movement in weeks.  All of you people who bought in at Nova expecting to make hundreds of %'s by arbitraging it on Poloniex are totally out of luck.  This is why you can't mess with broken wallet situations.  If you have too much hope that a certain wallet will be fixed you will end up holding big bags of junk.  Poloniex did not say what will happen to the coins that are on their exchange when the de-listing occurs, but since they do not plan to fix their wallet, I suppose the excess BTM will just be permanently stuck on Poloniex with no way to trade or withdraw it.
