Ethereum prices are currently falling sharply and the decline exceeds 70% of the stable price. I don't know for sure what the main cause is, but clearly Ethereum the market decline is influenced by Bitcoin and also the development projects that exist in the ICO. Because Ethereum's good source of income is from there, it is also possible that many users make sales. I do not know it all, which is clear we do not need to panic with the decrease in Ethereum to the price of $ 200 this.
