Cryptsy would be great to get on. I’ve emailed them multiple times the past few months (to Nicholas Mullech, their wallet manager) after they initially expressed interest in adding NuBits, with no response. Getting a wave of messages might encourage them to re-visit the idea of adding NuBits (and NuShares).
Changetip I’ve emailed before and had my message forwarded to Dan Held, but again no response. I’ll follow up with that one too.
