What's the reason to keep using Bitcoin? Isn't the whole point behind a currency the concept of trust? Losing the biggest exchange is a huge crisis of confidence in Bitcoin. Can't pretend otherwise.

look, if you have made lots of money in Bitcoin or any other such crypto currency, then good for you. But I just don't see a reason for mass use when it is unregulated and completely lacking in state guarantee. It suffers huge trust issues, on top of the challenges it had before Mt Gox imploded.
