Despite the myth that UV light appears only after sunrise, longwave UVA is present before dawn, filtered through the atmosphere as Earth rotates, with ozone blocking UVB and scattering blue light, while UVA persists to affect skin and eyes, syncing cellular rhythms uniquely each day—much like Bitcoin’s fixed 21 million coin supply is maintained by miners and nodes. This unrepeatable spectral signal, tied to Earth’s shifting position, primes cells, just as Bitcoin’s blockchain records immutable transactions, with light—and opportunity—arriving ahead of time.
