Individuals can invest in Bitcoin to help themselves, but as a country, they need to diversify their economy, create multiple streams of revenue, create employment opportunities, and adjust their economic policies to accommodate both local and foreign investors. There is a lot of work to be done to eradicate poverty in these poor countries. Bitcoin alone cannot do it.
The economy of a nation is much more complex than the economy of an individual or an organization, so we cannot apply individual economic solutions to the national economy.
Yes, for the national economy to improve and develop. We need to improve core issues such as fighting corruption, providing education and training, creating jobs by adjusting economic policies to attract foreign investors, improving infrastructure...improving people's lives...We cannot rely solely on financial investment and think that will improve the national economy.
In short, we need to clearly understand and grasp the causes of poverty in a country, from which we can come up with appropriate solutions to overcome the problem, thereby improving the economy. And Bitcoin is just an investment, not a magic wand, so don't abuse or exaggerate about it.
