a long time ago, ETH has always been rumored to be one of the coins that have the potential to surpass BTC. but unfortunately, the demand for BTC is always greater than ETH. in addition, the rise of bitcoin dominance a few days ago also became evidence that bitcoin was needed more than other coins, even ETH.
well, if one day ETH dominates, and replaces bitcoin, the answer is quite simple, just change your focus from bitcoin to ETH. Besides that, I think most investors have bitcoin and Ethereum in their wallets.
That's certainly true, mate. Ethereum may be far superior than Bitcoin in terms of its technological aspects. But the pioneer cryptocurrency is still widely trusted and adopted within the mainstream world. Because of this, Bitcoin has experienced a greater level of demand than Ethereum and most other altcoins on the market. Right now, ETH is far behind Bitcoin in terms of market cap. Considering the current circulating supply and price difference between both cryptocurrencies, it would take a lot of effort for ETH to get past Bitcoin anytime soon.
If the world's second largest cryptocurrency by market cap wants to experience an upsurge in price, it would need to deal with its issues first. It's still the day where many people are expecting Ethereum to adopt PoS + Sharding for scalability. Demand will gradually decrease until Ethereum does the right thing to boost its transaction capacity for mainstream use. Only then, investors will buy ETH in mass, resulting in higher prices over time. Despite this, it'll be nearly impossible to replace Bitcoin because it's too big to fail.
Nonetheless, I believe that Ethereum will do better by complementing Bitcoin in every way. Since it was mainly designed for smart contracts, it could serve its purpose well for delivering censorship-resistant dApps to the world. On the other hand, Bitcoin can serve well its purpose as a store of value as many people use it like "digital gold". As both cryptocurrencies improve over time, their position on market will become stronger. Hence, Ethereum might remain as the second largest cryptocurrency by market cap for years to come. Just my opinion
