Is there any chance that Ethereum will cost as much as Bitcoin in 2018?
There's a huge possibility but it is a serious matter in about ethereum because as of now bitcoin price is far way more than Ethereum's value so ethereum really need some huge boost to overcome or even reach the current bitcoin value.
You could say yes for the time being it's hard for ethereum to beat bitcoin, of course
seen in terms of the price between bitcoin and ethereum it is quite far,
so we don't expect ethereum to beat bitcoin
