Recently ETH got huge price increase. Is there any specific reason for that much of Increase ? 
Ethereum still the King of Altcoins, market capital is so high that even Bitcoin cash couldn't par but in terms of coin price, Bitcoin Cash is higher than any Altcoins.
So, Ethereum deserves to be pumped and people who complain about investing an expensive Bitcoin should go for Ethereum because the price is increasing and although there's a droppings but right after a couple of days it will rise back to the top bar.
Yup ethereum deserve a high price in the year 2018 it could be approximate $1000 to $1500 it also increasd the no. of ico project with eth based the problem is most of them became scam that have effect the price of ethereum.
In the near future ethereum will became more more popular in all over the world I hope the Developer will increase the transaction speed.
