I agree that if ETH went to zero it would cause BTC to rise. The reason I say this is because the amount of money currently in ETH. Wouldnt people see the drop and just switch over to BTC or perhaps they would wait and buy ETH at the bottom. I certainly hope this does not happen because Im new to the crypto world and the worst thing I see about the whole process is the fact the price fluctuates too much. As a result real investors are probably rethinking about investing. Oh well Im a newbie what do I know.
