Bitcoin Core's transaction backlog is building up again, which means fees are on the rise. Now, Bitcoin Cash is equally profitable to mine. Bitcoin Cash is suddenly a real contender.
If Segwit2x does not go off without a hitch, as I have speculated, it's possible Bitcoin Cash may be the emergency exit for the froth in the Bitcoin market, which could come down very hard if the 2MB hard fork either goes wrong or fails to happen.
With an impressive day like this adding momentum to the charts, we may not see Bitcoin Cash at $200 again until the next set of coins are granted and hit the exchanges.
If ever.
