Charles left bitshares before we even launched protoshares mining and before any of the innovation in bitshares was conceived. At the time we were still thinking bitshares would be proof of work. The final pegging solution wasn’t locked down until a year after he left. He does get credit for getting me initial funding and attention at the Atlanta conference.
Charles is great at raising money. He rides on coat tails of others tech innovation.
