The release of Casper could potentially boost the price of ETH and improve the scalability and speed of the network. However, is Casper is delayed we might see increasing dissatisfaction with Ethereum. Some big projects could migrate to competing platforms such as Cardano, EOS, or Neo, which would be a huge blow for ETH. It all depends on the news now. It seems that the market isn't reacting to that extremely oversold RSI.
