This is the key worry of governments with cryptocurrencies, and was the main selling point of them initially, before the whole crypto tech bro hype.
Yep. Arguably Bitcoin arose from the 2008 financial crisis and the following bailouts.
What I've never understood about it is that it seems so unlikely that it would ever replace a national currency, for two simple reasons. First, because taxes owed in a country can only be repaid in the national currency. Second, because government contracts will only ever pay in the national currency, from macroprojects, to maintenance contracts, to millions of civil servants. This creates both a ton of demand and a ton of supply for the national currency.
And that doesn't even take into account the role of the central bank and private banks in the money supply. Being highly regulated, there's zero chance that a private currency would ever be legally allowed to take hold there either.
Central bank digital currencies appear to have very little to do with crypto currencies like Bitcoin. Rather, they appear to be a mechanism to surgically induce economic stimulus when and where desired, like a more controlled version of the stimulus checks that we saw in many countries during COVID.
For example, they could directly credit your digital currency account with a certain amount of money that you are only allowed to spend on certain goods and services and for a limited amount of time. This would ensure that the money is spent and stimulates certain economic aress rather than being hoarded or invested.
Based on the way things are today, I can't make any assumptions that people in charge have any idea of what it takes to make a neighborhood ditch the car.
