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.
Ethereum and Bitcoin are two very different beasts. While many will compare the cryptocurrency aspect of both Ethereum and Bitcoin, the reality is that they are vastly different projects and have different intentions. Bitcoin has emerged as a relatively stable digital currency, while Ethereum aims to encompass more, with ether just a component of its smart contract applications. Bitcoin and Ethereum also cost their transactions in different ways. In Ethereum, it is called Gas, and the costing of transactions depends on their storage needs, complexity and bandwidth usage. In Bitcoin, the transactions are limited by the block size and they compete equally with each other.
