If you compare the two main cryptocurrency, namely Bitcoin and Ethereum, which one has the most promising future?
In terms of evolution, Bitcoin reached a maximum of roughly 4800$, whereas Ethereum reached roughly 394$: in other words, it is a potential increase of 33 % for Ethereum, but only 24% for Bitcoin.
Again you can see today in 2018 that Ethereum is growing more than bitcoin. Yes it btc price grew 2 times,but ethereum grew more and it's closer to maximum price then bitcoin. Btc today is like 11.7k(was 20k max) and etherum is 1.25k(1.5k max). You can compare that. And supply of bitcoin is limited,ETH has no limits. I can see by numbers that ETH has brighter future then bitcoin.
