21M – Classic Bitcoin Hat

Fixed supply. No exceptions.

The 21M design refers to Bitcoin’s fixed supply — a limit that cannot be changed.

No central authority. No monetary expansion. Just a hard cap, enforced by code.

It’s a quiet signal. Recognizable to those who understand what scarcity really means.

Minimal by design, but strong in meaning.
