I'm starting to believe that Ethereum could eventually surpass Bitcoin as the top cryptocurrency, especially given its strong ecosystem and the recent reduction in gas fees(Is this a rumour).
This is something we have been hearing for quite a long time now, some people touted Ethereum to be bitcoin killer, after all these years it should be glaring that it is definitely not possible. You might consider Ethereums ecosystem to be strong, i consider it to be centralized, more than ever after they switched from POW to POS. There is currently no competition between bitcoin and ethereum, but rather it is between ethereum and a few other altcoins.
There will never be anything that surpasses bitcoin which is by definition decentralized, centralized coins are easy to be discriminated against by governments and that is very dangerous, although the Ethereum ecosystem is very broad at the moment, it is not a guarantee that ethereum will surpass bitcoin, both people now prefer Solana to Ethereum, so the obvious conclusion is that Ethereum will never surpass bitcoin until whenever, especially since the Bitcoin ecosystem is currently under development, although it is quite annoying because it makes the network congested but maybe people will continue to build their projects on bitcoin relying on ordinals.
