This is not to say that ETH can and will be the only winner. Its possible that Cardano, DOT and some others will have part of the market share. I own some Cardano, Polkadot, Luna, etc. But I its more of a hedge than anything else. Good thing is, if they go worthless big deal, if they work out, they can be multi trillion dollar assets so its a decent bet. But I think ETH should be the Windows of the metaverse, there might be Mac OS and Linux, but ETH will own most of the market
This NFT craze is only increasing its dominance, more and more people are getting used to Metamask, ETH transactions, ETH prices, how to mint NFTs, etc. And they will teach other people that. If they all of the sudden have to learn a whole new way to do things, its annoying. I split my hair out dealing with the DOT validator system, so much so that I gave up on it and will earn no interest on my DOT. I bet lots of people will have no patience to learning whole new systems
Its funny, Cardano used to be the "eth killer" now they incorporated the ability to port ERC-20 code into Cardano so people dont have to learn Haskell. Thus further increasing the relevance and reach of the Solidity language
It reminds me of when Steve Jobs allowed Microsoft to develop Microsoft Office for MacOS. He didnt had a choice, people were used to it and businesses needed instead of learning a whole new office suite but it further solidified Office as the office suite for the world
