Is right to say that, ETH would be nothing without BTC? Because most of time, when I look into an ICO its accept ETH and BTC. I think that is the BTC that gives 'value' to ETH, but I don't know for sure.
Many are saying that there will be a coin flip and that Ethereum will overcome bitcoin. But its sad to say that Ethereum had just crashed while bitcoin continues to go up. Ethereum was being used by traders so that they can gain more bitcoins. In the end bitcoin will never be replaced , not in this year.
