What factors can cause major fluctuations of Ethereum price? and how it will impact other ethereum blockchain based tokens/coins?
As far as I know, there are two main reasons why the price of ETH is down.
1. ETH goes down because the bitcoin price falls. When bitcoin goes down, all altcoin things fall down. That is 100% certain from now until now
2. The ICO sells to ETH after the end of the ICO to take the money to fund the development. This makes the price of ETH impossible to go up because of the continuous ICO take turns selling ETH
