Flexcoin, a bitcoin exchange has been shut down since they failed to understand that financial transactions need strong consistency and eventual consistency is not sufficient (In this context: ” all services should have had the same view of the user’s Bitcoin balance but they didn’t “).

Alex Daley (from Casey Research) wrotemultiple thorough and bearish posts on Bitcoins, he agreed on the premise of technology but referred current status as hype.
