Will ETH cross BTC one day ??
they are crossing each other everyday,
actually they need each other for the price to grow.
but if you are referring that will ETH be cross the line of the price of BTC! this will never happen!
Haha you got it right their, this two are interfering everyday and everyone are always looking for their price on their folio, but in the future Bitcoin still will be the king of all, and prices will be win by Bitcoin as always, Bitcoin is also first accepted on every places then next is ETH so I think ETH won't cross the line..
