We don't know what will happen in the future. We may see other assets which has even more Limited supply than Bitcoin. We cannot rule out the possibility. But that doesn't mean it will have same kind of market adoption as Bitcoin.

So if you are talking about only scarcity, it is possible. But if you are linking scarcity with value, less likely to happen. But you never know.

From my personal experience, Bitcoin has given the best return if I compare amongst all asset classes I have invested in so far.
