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.
I do not invest in ETH or Bitcoin, but I see that ETH has more potential for development than Bitcoin. ETH can add several thousand dollars more quietly, but Bitcoin is a difficult thing when many investors are trying to pull Bitcoin down.
