Only 'small' issue with XCP, is our lack of exposure. Only 2 nerds and 3 geeks know about it, and we can see tons of inferior coins (functionnality-wise) getting an insane value, just because of the hype. This is the only potential point of failure of XCP as of today.
Don't forget that Adam from Let's Talk Bitcoin is starting
LTBcoin on top of Counterparty. This project will be launched soon and he's already talking about it in every show. I guess we will see quite an interest in LTBcoin and Counterparty once this went live.
