Bitcoin has no team or owner for a good reason. It's meant to be a decentralized coin that goes against the banks and government's way of thinking and if there was someone who owned and was able to control the technology, it'll be no longer be decentralized.
There are multiple core BTC developers though that work on Bitcoin Core, and they help implement new technology and ideas into the system, with the latest change being the lightning network.
I don't see bitcoin merging with an alternative coin but as they will improve their blockchain to make it faster and consume less energy
Yes. I agree. BTC will never merge or form with another coin, especially if it is a centralized coin because a lot of the developers won't agree and implement the new technology.
