Right. Satoshi Nakamoto created Bitcoin. He's a genius. Bitcoin systems and communities are working perfectly, and everyone is crazy about Bitcoin. But what happens if someone creates a blockchain that is faster and better than Bitcoin and puts it out into the world without any greed, as Satoshi did? Are people going to ditch Bitcoin away? In that moment, we're going to see a blockchain that's performing better than Bitcoin and is perfect for decentralization that everyone emphasizes. What will happen?
We are still waiting for a faster, better and more secure blockchain. Bitcoin Cash was supposed to be "faster and better" because of the bigger mining blocks, but it failed. Ethereum was supposed to be "faster and better", but it's not.
Having less transaction fees and faster confirmation time means that such blockchain will have to sacrifice a little bit of the security, which is an instant red flag.
What will happen, when such "better" blockchain appears? Well, the crypto enthusiasts will adopt this blockchain and reduce their usage of BTC and the BTC blockchain. There's no drama here. The world of crypto is competitive and I don't find any problem with this. Bitcoin will remain "the first cryptocurrency" and it will become a legend.
