Bitcoin might not be dead, but until they figure out a permanent solution to prevent exchanges from dropping like flies, I'd say Bitcoin is in a deep coma.
Self-regulatory organization (SRO), the board of which would be elected by exchanges and perhaps the bitcoin foundation, which would be voluntary for exchanges to join, which would provide supervision and guidance. Exchanges that didn't join the SRO could still exist, but the public would have the option of purchasing bitcoin from one that had that extra layer of supervision.
