It's true that the market cap of ETH has increased manifold since last few months and the price also increased to an optimum level. It shows that many people now showing interest on ETH and they are diversifying.

The market cap of ETH is only 8 billion USD less than the bitcoin. I believe that is because of the technical superiority of ETH over bitcoin has paved the way and earned a lot of respect among the investors.  I have started investing in ETH when the price was around $120...I regret that I didn't buy ETH at the initial level when it was just few dollars. But better let than never.
