False. Who uses bitcoin as an alternative to fiat to begin with? Practically no one. It is hardly even used in El Salvador. Nor in this forum itself will reach 10% of regular users who use it as an alternative, paying their petrol, supermarket, etc. with current satoshis without previously converting to fiat.
As for understanding the financial system, I would say that the percentage is higher because people realise that fiat is devalued due to monetary policies, while bitcoin is limited but there are many people who buy bitcoin like they buy fashionable stocks and the shitcoin of the moment, and this does not stem from a deep understanding of how the monetary system works.
I would say that maybe you even yourself do not have a deep understanding of how the monetary system works. Can you tell me what M3 is without looking it up on the internet? More than 90% of people on this forum wouldn't know, and we here are supposed to know more than the average citizen.
