Xcp - mature projects (sjcx bcy fldc ltbc), interesting new projects (bitgirls Japanese TV show, orb, blockfreight, force of will--the 4th most popular trading card game in the world with a movie coming out), low coin supply (2.6m), deflationary money supply (no mining, only burning), active community, interesting tech in active development ( micropayment channels, smart contracts), based on bitcoin (btc security), new exchanges (zaif in Japan, innocoin app), awesome wallets (too many to name)

Plus xcp has a very low market cap--only about 16m dollars AFTER recent run to .01. also some of the oldest most respected names in crypto are supporters -- ver, antanopolis, Adam Levine... I'm riding counterparty to .05
