Using the word "pump" implies that the price moves are artificial, being manufactured by a few people. This isn't happening with Bitcoin...and I don't think it's happening with Bitcoin Cash.

So my answer to your question is "No".

Bitcoin Cash was always going to take time to succeed or fail, it takes time for the miners to want to accept those transactions and with that slow adoption comes faster confirmation times, which in turn offers more confidence to speculative investors and the cycle goes on.

I hope these two can coexist...if they both exist harmoniously we all win.
