As you can imagine, several factors will influence the choice including:
- ease of adding the coin
- trading volume
- bounties
ElDido your and DarkEmi are AWSOME - happy to see you here.
Hope you will help the XCP community as you helped Mastercoin.

Please do your DD on XCP - it might influence your choice.
