You are not comparing apples to apples. BTC is comparable to gold or US treasuries. How often do you transact in physical gold? What is time taken from a piece of gold in your pocket to cash to coffee? However, you can transact in paper gold eg the ETF GLD in microseconds with comparatively much lower transaction costs (settlement is still not immediate). How often do you transact in treasury bonds? Try paying for a coffee with your treasury bond. Let’s see how many days that takes. Comparison with USD (ultimately representing US treasuries) on number of transactions basis is not useful.
