vote for the coin on comkort.com! maybe they add it - i dont know. arkenstone has some potential if only some people see that. it still deserves a chance. i like to compare it to unobtanium and other rare coins.
It's rare like UNO and a Sha256 coin but that's where the similarity ends. ARS has a 2% premine, or 4000 coins. That's currently about 24% of existing coins.
Still, I have a bunch of these and would not mind seeing it added to an exchange.
Comkort would be good. I think allcrypt would be a better exchange for ARS. There is no voting for Allcrypt. Just email them and ask. I would put some coins out there to help kick it off.
Btw, in it's current state, I'll give 1 Uno for 100 ARS, up to 5000 ARS.
