Yes it's true that Ethereum and Bitcoin values fluctuate around the same!
But this is nowadays. There aren't many news about Ethereum!
We already have seen in the past ETH running and Bitcoin stable!
When some news come out you will see ETH running and BTC stable.
There will be a big hard fork next month. If it is successful, the price will rise a lot.
Price will rise for which? Bitcoin or Ethereum?
Both will rise a lot in the near term.
I agree with that. And possibly the Bitcoin Cash.
There are too few users of Bitcoin Cash at the moment. I think it needs to attract more users.
No, 1/10 transaction of Bitcoin has transfered to Bitcoin Cash when the Bitcoin system has problem slow confirm transaction in past days.
It proved some Bitcoin users also used Bitcoin Cash for their transaction instead of Ethereum or other altcoins.
