At 0.11 BTC(current price of Ethereum) , Ethereum is already 65%~ of bitcoin's market cap , considering that there are 6x more Ethereum coins then bitcoin coins.
Do you think that Ethereum can pass bitcoin?
That's the question you should be asking yourself before investing in Ethereum as 30% rise against the bitcoin will make it's market cap to be worth the same as bitcoin.

I think this year is going to be the year of the anonymous cryptocurrencies, such as Monero and Dash, as regulators enter the free market and people will need to find some alternatives to escape from regulators.
