Take a look at Bitcoin Cash price in this chart. Nice pump indeed, but what's interesting, I believe that this one has a very specific reason.
I believe that this one was made by the miners.
They exactly knew when the BCH mining difficulty will drop. They knew, that once this happens, they will be able to mine Bitcoin Cash 3 times faster than Bitcoin. In order to maximize their profit, they did everything they can to pump the BCH price.
But there is a problem.
In 3 days and 19 hours (and this gets shorter with each new block) the difficulty will rise by over 200% - which will make again BCH not profitable to mine compared to BTC.
This will not be good for the BCH price, as it's in a steady decline now at $684.
My opinion: I know that many believed that BCH is the new, better Bitcoin but there were many copies of BTC before that stated the same. This one has much better PR which allowed the miners to make a great profit on people that believed in it, bought it at $900 and are still buying it at $680.
But once the profitability will drop, I think it will return to around $300-$400 levels and then slowly decline from there. It will be a great pump and dump coin though.
Please not that it's just my opinion, probably the safest strategy now is to hold both BCH and BTC to see which one will win.
See you next time!
