This year we will see 90% of the bitcoin supply mined already. Between now and 99%, which is in the year 2035 there will be a few halvings, and I think the mother of all happens somewhere in the middle. Past that, there's not much left to make any significant effect.

By the year 2048, we have 99.9% of supply. The next 100 years to the year 2140 (or as some predict maybe even earlier, but just a few years) is a 0.1% increase to 100% of all bitcoin supply.

But we also know price does not immediately follow these milestones, it may take some time for these numbers to sink in before people, retail, and institutional investors and even countries to buy in.
