If everyone in the world gets into crypto and cryptocurrency will become an official global currency, do you think bitcoin then will stop depending on fiat currency? Or will it just co-exist with fiat?
Probably the latter. I don't think bitcoin will be a global currency anytime soon or reach a level where if someone ask: "how much is one bitcoin in dollars?" and they reply: "I don't understand? one bitcoin is one bitcoin." The reason for this is people tend to prefer tangible over non-tangible things such as crypto.
