Bitcoin and Ethereum are two of the most popular digital coins today. In terms of value, bitcoin is much larger than ethereum, but in terms of potential, ethereum is quite capable of dealing with bitcoin. So you think which one is better?
Well, first of all, you must understand that there is no logical comparison among Ethereum and bitcoin.
Bitcoin is created as an alternative to regular money and is thus a medium of payment transaction and store of value, Ethereum is developed as a platform which facilitates peer-to-peer contracts and applications via its own currency vehicle.
If your only sense for comparing both is the market capital, then my answer will be "It could be possible, but it will take years before that happen".
There are a lot many uptrends around Bitcoin, with lightning network coming in place and FOMO money driving in Crypto, the Bitcoin dominance is supposedly to increase back above 50%.
