cultural heritage are things invented in the past that can be considered as common asset of mankind, for current and future generations.
Some example:
Invention of Arabic numerals and its implication in modern mathematics.
The spirit of Greek / Rome empire
US Democracy (disputed: may soon to be lost due to communist/socialism globalist deep state take over)
will BTC be considered cultural heritage? if so what are its merit?
in the face of eternity culture is worthless junk as it can be created in unlimited different forms,
like music, langauge, art or food recepies.
so don't overvalue "culture"
what in truth matter is what lays a ground for a fruitful realm.
