The adoption of cryptocurrencies is certainly expected to make it easier for users to use or transact directly, unfortunately currently there are too many obstacles and challenges that make the adoption process slow, in my opinion the most important thing is to immediately legalize cryptocurrencies so that they can be easily developed and equivalent to fiat.
it will be very hard before you will see a country that will legalize a cryptocurrency so any country that tries to bring such idea of legalizing of cryptocurrency generally or any country the country will be suppressed by other countries because they are against bitcoin already so that is why I think that accepting bitcoin as a legal tender by adopting it it will be very hard
