Currencies are convertible ..the idea of making them non-convertible is going back to sixties .. eg pegged to #gold or #bitcoin ..
Currency represents the economic activity of a financial system - weather it is a nation or a security..
This also means you can't have your savings in currencies - you must invest in #assets .. stocks , bonds , real estate , #gold or #Bitcoin ..
Those who keep their money in currencies are likely to get poor .. because good currencies need more liquidity and bad one lose their currency status ..
Everyone gets it but poor can't invest in assets because there is a minimum threshold for buying an asset, and there is a transaction cost ..
#bitcoin fixes this through #sats .. extremely small chunks of most durable asset that one can obtain practically without a transaction cost ..
