Its quite a  pleasure to watch your invested coin to see a rise in price. ETH had raised to almost 30% this week which was a delight.
I think the reason behind this is the people investing in ICOs. Almost all the ICOs use ETH as a mode of payment. So people buy ETH and then invest it in them. ETH already is a potential coin and has the ability to cross a million dollars. Though it would take ETH a few years to reach that milestone it has the capability to be at that level. Time will show us how far it goes.
