That will never happen, bitcoin is go-ahead, eth will never pass bitcoin on price
Who knows, man? Ethereum is an extremely powerful altcoin, and more and more people support it and want to buy and hold for long. I can easily admit that the time when ETH will overcome Bitcoin will come.
So you think that this time will happen in future? That etherum will be "better" than bitcoin in price and amount of users? For me it COULD happen but i don' think that it will happen in near future or even in future.
