I think Bitcoin can help a poor country or nation by protecting it's asset from hyper inflation and economic collapse and that if the country invests on it just like what El Salvador, Bhutan and some US states did. Bitcoin being a decentralized asset to a specific country will ensure it's people that the said asset is safe and secure.
The causes of hyperinflation and economic collapse are government corruption, unfeasible economic policies, imbalances in domestic supply and demand, unemployment, indiscriminate money printing...and hundreds of other reasons that cause economic collapse and poverty. Can Bitcoin prevent corruption, balance supply and demand, or create jobs and ensure income for everyone? Bitcoin cannot improve any of the above, how can it be said that Bitcoin will help a poor national economy?
El Salvador has been investing in bitcoin since 2021 and has made 2 or 3 times profit on its investment, why do they still need to borrow money from IFM to save their economy?
Bitcoin is not God and it cannot help poor countries, don't exaggerate.
