The historical aspect of the article is mostly accurate. The issue seems to be with using Bitcoin as a currency for every day transactions. The transaction rate still hasn’t been solved. Bitcoin still has a role to play in international finance, it can replace the need for a reserve currency at all due to the distributed ledger. In this way, look for it to replace the functions of the Bond market first. It is ideal for keeping track of large transactions over time between nations and companies. Also, the key to a reserve currency since Bretton Woods has partially been that energy has been priced in U.S. dollars. Another advantage for crypto, for those same energy interests that seem to own everything already, is that more energy is consumed as financial activity happens creating a sort of symbiotic relationship that the U.S. dollar had for some time. This inherent fact might be why it continues to survive various crashes.
