Our goal is to add coins based on community demand.
Here's how it will work.
Round 1: Every week we will run a poll on bitcointalk. The top 3 vote getters move into a
bittrex.com poll.
Round 2: The poll within
bittrex.com will consider votes from active users only. Our inaugural poll within Bittrex will have SYN, XPM, SBC, MRS, PANDA, and whichever coins makes it out of Round 1 this week.
If you have any suggestions for additional coins to add to this poll, please ask.
