as you said, a spike, not really due to organic growth, Roger pumping his own coin

just as any investment, people take profits, so if something does cause a coin to pump alot, it'll dump soon enough, unless there's a solid reason for the pump.
which in BCH case, there really isn't, is there? should be organic growth while taking market dominance from BTC, logically
