I am surprised that Poloniex have not stop trading in MNTA with the wallet not working for such a long time now. At the moment, not surprising deposits and withdrawals are "temporarily disabled". Other exchanges would have terminated trading on inaccessible altcoin wallets for a significantly less period of time.
I am also a bit surprised that there is some albeit light activity on MNTA-XMR on Poloniex. Considering I see no direction/vision for the coin at all. Remember this coin has nothing to do with the moneta/zerocoin protocol thing that kicked off last year. This coin would appear to absolutely pointless and worthless now. So any trading activity on Poloniex seems very suspicious IMHO.
