This is a fair point, but lack of volume can only be solved by adoption and investment, which will happen eventually if the system remains otherwise superior. How many more Mt. Gox events will it take before people leave the centralized exchanges?

Yeah, there's been a lot of interesting activity on those exchanges lately as well, hasn't there? That's what prompted me to go ahead and migrate over to a bitshares wallet.
