I'm not saying Ethereum (ETH) can't compete, they can with all the potential of their ecosystem. However, surpassing Bitcoin (BTC) adoption, remember I used the word "surpass" is simply not possible. I agree that Bitcoin (BTC) & Ethereum (ETH) have completely different markets, I also agree that Ethereum (ETH) has more gateways of opportunity.
Even though ETH has more gateways it does not mean it can surpass bitcoins. Bitcoins always have and will be the mother coin with higher market cap and will be people's favourite always. We can't deny the fact that without bitcoins, nothing was possible. Imagine if bitcoins never came into picture, would there have been blockchain or any other crypto?
Institutions believe in the cause to bring crypto revolution and they will invest in this cause knowing this cause can also make them earn good chunks of profits.
For ETH, people will hold it and so will the institutions but this does not necessarily mean that the adoption for ETH is higher than BTC.
