Bitcoin is finally approaching a major milestone of 20 million coins.

At the current mining pace, it is expected to reach this milestone in about a week.

This is actually a very symbolic moment.
Already over 95% of the total BTC in circulation, demonstrating how mature Bitcoin's design is.
Satoshi Nakamoto is the person who hardcoded the absolute cap of 21 million coins into the protocol, contrasting with central banks' printing, achieving a completely predictable and immutable supply curve.

Satoshi Nakamoto is not just a developer but can be seen as a thinker who technically implemented the concept of "hard money."
This fixed cap is a foundational value proposition for Bitcoin maximalists, and proposals to change it are viewed as undermining core values.

Bitcoin's scarcity is often compared to gold or oil, but there is a decisive difference.
Goods increase supply through higher prices or new discoveries, but Bitcoin's issuance cannot accelerate.
Its supply curve is completely transparent and unchangeable.

Approximately every four years, the halving reduces miners' rewards, keeping the current inflation rate below 1%.
At the current pace of about 450 BTC mined per day, 99% of the supply is expected to be mined by January 2035.
The last full Bitcoin is projected around 2105, with partial issuance continuing until around 2140.

When considering what Satoshi Nakamoto was, the thoroughness of this long-term design philosophy becomes apparent.
The milestone of 20 million coins reinforces the story of Bitcoin's scarcity as new supply diminishes.
At the same time, it signifies a long-term shift for miners toward a fee-driven revenue model, ultimately affecting the network's security and economic sustainability.

By the way, even the ecosystem around Bitcoin is rapidly evolving, such as a major exchange integrating prediction markets into wallet features.
Amid these developments, Bitcoin's supply rules remain unchanged.
I believe that is the greatest strength of Satoshi Nakamoto's design.
