You guys too, please go to
https://poloniex.com/coinRequest and help out XDE by getting it listed at Polo at least... It seems Richie is too busy to add any new coins nowadays... I only saw 1 or 2 new coins added very recently at Trex...
I just submitted my request to Polo. It is extremely important that we provide a good justification of why Poloniex should list XDE. Please make sure you include that in your submissions.
