The problem with Altcoins are they're underacted and never given a chance to pump their prices. Moreover, Bitcoin Cash has already been pump although a lot of people were not happy on it as they tagged it as a Big Joke that people supports Bitcoin Cash than any other Altcoins.
Last August this year, the birth of Bitcoin Cash for some analysts is the destruction for Bitcoin but the result is opposite, actually it helped Bitcoin value to rise more to the top of the graph and now Bitcoin Cash begin to show it's intention that it would be likely the threat of Bitcoin and Altcoins as well.
Ethereum value was actually lying low flat for a long time but Bitcoin Cash has the pump than Ethereum.
I think there will be a reason behind this, thus, Ethereum team are working hard also to keep their coins rise it's value but today isn't the day.
