Bitcoin's main strength is not its speed, not its block time or size, not its mining algo, suppy cap... I am not saying bitcoin is an outdated tech though. It has the highest dev activity out there. Most of the altcoin devs are still copying core's work to create their own blockchain and that's a good thing. What iam saying is Its main strength is its immutability. Everybody knows once its on the block chain, it is done. There isn't a way to undo it.

In other words, bitcoin is the true decentralized/leaderless blockchain. (unlike eth or bcash or almost any other shitcoin out there)

Bitcoin didn't do partnerships, satoshi didn't buy google ads or hired shills to promote bitcoin... Everything happened because... bitcoin was good, people thought bitcoin was above partnerships, CEOs, leaders, corporates. People bought it and exchanges had to list it, businesses had to accept it as a payment method. Nobody signed nothing. That's why it is not going anywhere (nowhere bad) as long as it stays that way.
