We need to know that crypto doesn't perform any magic. If the country is poor, the government should help its citizens upgrade to a certain level where they can help themselves.
If you live in a poor country, how can you afford to buy crypto to help someone? Crypto isn't always the answer to everything. For some, spending a little on cheap coins might pay off, and they might have a big success story, but that’s not always the case.
Crypto doesn't end poverty, in fact, it can make you poorer if you don't know what you're doing. if you have the right knowledge and resources, it can help you make a lot of money.
I think the question is already answered by yourself. Is quite obvious that Bitcoin would only help those who help themselves. Because it is when you know the value of something that you can make use of it very well. it will be very hard for a country to achieve success in something that they don't know anything about, more especially Bitcoin because without a proper knowledge and understand a country would never afford to make it through Bitcoin due to the risk involved.
