Bitcoin has come a very long way since its launch and the hurdles it has faced has made it wax stronger, that some of those countries who adopted it courageously still benefit from making it a legal tender, even though it has leaned more towards being a strategic reserve asset and as an optional legal tender with fiat currency still an option of choice.
El Salvador remains a good case study as they no longer look at Bitcoin use same way, but have learnt to be dynamic from making Bitcoin mandatory to making it an optional use for transactions and payments and investments.
El Salvador is the only country that has adopted and made bitcoin legal tender with the expectation that it will help improve their economy. But after years of adopting bitcoin, they were forced to abolish that regulation in exchange for a loan from the IMF to save their economy. This shows that they did not benefit or receive any significant advantage from the adoption of bitcoin
To date, just like us, the only benefit they have received from bitcoin is the profit they made from investing in it.
Countries like the U.S, Bhutan also have strategic Bitcoin reserves while other countries like Russia and China and Argentina and UAE are in line to make it a strategic reserve asset that can't be overlooked.
Bhutan's strategic bitcoin reserves come from its utilization of cheap electricity for mining. Meanwhile, the US only uses bitcoin seized from criminal. None of them allocated national budget funds to buy bitcoin
