Bitcoin IS money. Though not for everybody yet.

Not relying on 3rd parties. Even when using CEXes they are just tools.

Always there until people sell. When they sell to somebody else, the buyer enjoys it. It is not gone.

This is hard part. Because BTC has no physical representation in most cases.

When using p2p it is just simply superior. In use-cases involving little more complexity i.e. with multiple parties and inheritance schemes it becomes priceless.

Nobody knows but it is on track to be recognized as money for more and more people. It may be easily seen, a nocoiner few years ago becomes a user who begins to think of Bitcoin as an asset. This is powerful even if this past nocoiner wants to sell bitcoins for something.
