What do you guys expect of Bitcoin?

I have never really understood why people were that optimistic about Bitcoin. I don't want to spread FUD or criticize or anything, I would just like to hear what you have to say about my thoughts.

When Bitcoin was new, it was a big thing. Decentralized digital money. But then Ethereum came and took the next step by essentially allowing anything digital to be decentralized. The token Eth was just the currency to reward the network maintainers. Now there are even more efficient and flexible protocols such as Solana, Avalanche, Harmony One, Polkadot, probably many more.

So I am just wondering, why, really, do people still expect Bitcoin will be relevant in 10 years from now? Again, I know this sub is very protective of Bitcoin and I am not trying to provoke FUD. I just really can't see why people would want to use Bitcoin to build the future of finance and would like to understand why so many people still believe it will stay around.
