You have to look at the country of Venezuela, when the world economy is not clear.  Venezuela uses cryptocurrency as a solution to the economic crisis by backing up the country's finances.  The digital currency, known as the petro, which was later followed by the sovereign bolivar, is claimed to be the first in the world to be used to support the oil-producing country's physical assets.  and bitcoin also came in early January when the world was in crisis. In the midst of these crisis conditions, people wanted another currency as an alternative.  The emergence of Bitcoin, Ethereum, and various other cryptocurrencies has slowly continued to grow in terms of price and market capitalization.  This evidence shows that people are increasingly looking for cryptocurrencies as alternatives during times of crisis.

Let's take an example of a small business that wants to sell smartphones and needs capital. The company would have to go to the banks to apply for a loan. The owner of the company gets the loan but it is not enough to start his business for which he decides to buy Bitcoin with that money. When the company saves enough to buy its merchandise, it puts its smartphones up for sale and asks to be paid for with Bitcoin and crypto. This entrepreneur does well in his business so he can hire more people and expand his business in several cities of the country.
The paradigm is in the good work of people in adopting Bitcoin and making their projects and the opportunities they have come true.

But a country which is friendly to bitcoin is a country which is also open to technology and innovation.
It means this country will have the attention of entrepreneurs, developers and investors from different countries who also have interest for bitcoin. If we are talking about a developing country it can boost its economy and population welfare for sure. You are right when you say it's responsability of the local government to create the best possible atmosphere for the local development, so it's also the government's duty to have a friendly behavior towards bitcoin or not.

I don’t know about the one of escaping poverty, can Bitcoin really help people escape poverty? Since it’s an investment there is no guarantee you’re getting profit, it can take long before you make profit. I will say that the main part is transaction, it eases transaction, although there have been complaints about it, but I heard that during the last protest in Nigeria that their central bank blocked the accounts of protesters and they had to make use of Bitcoin to support the protesters.

So, that’s one of the areas that Bitcoin is being helpful. As for making people rich, first you need to have money you’re going to invest in Bitcoin, and when you do that, you will need to have patience for the price to go up.

Blockchain is a technology that can help countries get out of poverty, but for that to happen the leaders must be willing to do what it's best for the country.

Country-wide implementation is very hard even for well-developed states, however with small steps it can be an attainable goal. If I were a politician I would put so much more emphasis on tech.

I've recently learned about some automation cases based on RPA technology and I must say it is amazing how much time can be saved. Blockchain can not only save us time and money, but add a whole lot of transparency on top of those.

but it is a pity that some developing countries still do not fully accept bitcoin. This relates to the issue of regulation given by developing country governments. For example, in Indonesia, Bitcoin is legal and allowed only as a commodity trading and is not allowed to be a legal means of payment for several reasons about its high volatile risk.

The role of cryptocurrency in economic growth in developing countries can be very important if it can be implemented in the right way. As Bitcoin is considered an acceptable medium for many transactions, it is possible for any country or organization to buy and sell products or services, improve business, and develop through the use of sophisticated technology. On the other hand, if it becomes a widely accepted medium in the world, it will facilitate the economic development of developing countries. In addition, countries with various economic sanctions can easily use Bitcoin to trade with the outside world through the use of Bitcoin.

If you can call the growth in terms of transparency then i would say it will help a country develop by eradicating corruption and have a transparent process.

Bitcoin can help people escape poverty if they are willing to take advantage of the free market opportunity bitcoin and the cryptocurrency market is providing and if you are able to do that then sky is the limit but to reach those poverty stricken places it will take a long time and the local government has to intervene in giving them basic internet facilities and so on for that to happen.

I don't think that Bitcoin or any other crypto can help economy of any country if it's not officially introduced into economy and financial system and regulated. As far as I know no county has done that.
However, Bitcoin can help fight poverty on an individual level and every person, no matter if lives in developed or underdeveloped county, can with help of Bitcoin improve personal finances or even find some crypto related job.
