Nope.
I don't see it would happen, altcoins are better I guess even though it fails in decentralization.
This is theThe thing about cryptocurrency is it not the decentralization the core value proposed when the first cryptocurrency were created? And all these altcoins follow such core but since the altcoin developers are greedy, they wanted full control than implement the what is intended of decentralization.
In Bitcoin, we can't access our wallet by just connect the wallet to any sites. In altcoins, it's possible, this make easier to interact with every projects.
Bitcoin can connect through web3 application but since Bitcoin prioritized security over ease of use, developers chooses not to do such feature to avoid certain hacks during the process. And it looks like Bitcoin developers are right about their decision since we have seen lots of altcoins hack due to this connecting feature.
We're talking about a "system" not just a "currency".
Is not Bitcoin a full monetary
systesystem? If you look at its structure, you can look at the history how altcoins take its structure from Bitcoin monetary system.
