actually it doesn't only happen to ethereum but some other altcoins also go down together. I don't know what's going on with the crypto market lately, but I think ETH still has a chance to pump $ 200 before the end of this year.
True, I am also still convinced that the price of ETH will rise again at the end of this year, although in the middle of this year ETH has experienced a very severe price decline, but the potential to rise again at the end of this year is always wide open for ETH, I personally am always optimistic against altcoin ETH, because ETH altcoin is the best platform in cryptocurrency.
