Any information why?
This is a huge surprise. Just outrageous! It is going to be interesting to see just how Bitshares engages Bittrex on this issue. Either it's a mistake or it's war, and only effective discussion and negotiation can lead to a reliable conclusion. If BTS is what it purports itself to be, they will get to the bottom of this.
Considering all the information available as of today, it looks like an obvious and blatant preemptive strike by Bittrex.
Bitshares needs to respond with the hardest hitting marketing campaign possible. No more Mr. Niceguy.
