I'm more afraid of low trade volumes and possible lack of interest in the coin and services, sort of "Mastercoin illness".
I think that is the main obstacle for any coin with 2.0 features like these - they are great features if they get used but there just aren't that many people in a position to use those features who actually know about them and are willing to take the risk of dealing with cryptos, but I'm quite hopeful for Syscoin due to the close working relationship with Moolah, which I think gives this coin a much better chance of getting people to actually use all of its features compared to most.
