I have bought BNK this morning, so it is going down becouse of my luck
It is still 60% up from yesterday price level even exchange support is very limited. Hitbtc is not a good exchange due to insane withdraw fees but when this this exchange will become functional than it will be nice for this.
It is also possible to send ETH to your Spectrocoin wallet and purchase BNK with it at Spectrocoin. But Spectrocoin probably also works with withdrawal fees and minimum withdrawal amounts.
