I was wondering about this. many people want to encourage crypto adoption in their country. but whether when adoption happens they will use it. or they are more comfortable using FIAT.
an example is a country has fully adopted crypto and they released their own stablecoin. they also legalize some other big crypto coins like bitcoin, ethereum, and some stablecoins like USDT or DAI. and you become one of the citizens of that country. which one will you use for daily transactions. stablecoins issued by your country's central bank, or mainstream crypto coins like bitcoin. or privately released stablecoins such as tether. or keep using cash because you are used to it. and give the reason why you chose that coin.
Pretty tough question for me to be honest. So far i still see cryptos only as an investment asset or as an ecosystem that privides a lot of functionality and possibilities for developers to create Apps on top on like Games for example. If my country would introduce an official crypto stable coin that is pegged to my national currency then i am not really sure if that would change anything? It would probably mean that you have to transfer the "real" currency, for example Euros, to get the equivalent amount of crypto-Euros on your wallet. So i don't really see the benefit for having a crypto euro then. What would make a different is, if the normal euro would completely disagree, but i don't think that will ever happen.
