Bitcoin can not help them.
To solve hyperinflation, countries need to implement strict monetary policies such as raising interest rates, reducing the money supply, and saving government spending, as well as maintaining currency stability. Is it possible with Bitcoin? I think it depends on the government's policy with the arrangements. Indeed, systemically scarcity with the need for value will increase and it can help improve the economy. But are they capable? Maybe if given but to get with the current economic conditions is very impossible.
