Looks Minex team doesn't make persistent efforts in adding MNX to other exchanges. Plenty of coins that appeared much later are already listed on Binance, Bittrex, Kucoin, you name it, but MNX is still confined at only one middle size exchange.I think that's very sad.
You mean plenty of tokens running on top of ethereum. This is a new coin with its new mining algorithm, it is very different. This might be the reason why it is so difficult to be added to a big exchange.
