I don't really think Ethereum will do what it did last time. Wasn't it just pumped up because of ICO's?
No it was not pumped up due to ICO and was rather having a good market because of fast pace of growth, stability in price and the rise in Bitcoin as well. Keep a watch this time and as Bitcoin rose, ETH will follow sharp.
Yes the bull run in the price of ethereum was because of the bull market and it increased the price too much but the adoption of ethereum by the ICO projects also helped it to increase in value as many people start to buy ethereum to invest in these ICOs.
