Ethereum is getting bigger and better each and every day, The market cap reached nearly $20 billion and the trading volumes are now higher than bitcoin's.
That's ture. it takes more than 8 years for BTC to be $20, while it is only 2 years for ETH. However, BTC is the pioneer of crypto currencies that we should remember.
This does not necessarily signs that ETH is better, since bitcoin was the firs crypto currency is is to e expected the path was harder a the beginning for bitcoin and as altcoins have gained acceptation then their prices are able to move faster than bitcoin in the beginning stages of bitcoin life.
