Correct, and this is not a theory that we are formulating on our own, this is a historical fact, we have seen this scenario many times in which a government for some reason or another begins to increase the money supply to the point inflation goes out of control.
And things get so bad the only way they see for solving the problem is to keep printing money, but this is only a temporary solution as we know that the more money is printed the more inflation grows, and it gets to the point in which no one wants to hold fiat and some even begin to use barter as a way to exchange among them for goods and services.
I think nothing can solve the poverty issue - the countries which have developed have progressed - those which are left behind will remain behind.
In our country there are so many issues - people are tired and sick of inflation. One thing ends and a new issue is standing with open arms. I see not end to poverty.
A country can solve the poverty issue since there is a majority of honest, conscious, patriot and educated people in the region, so their ideals and ideas will prevail, overcoming difficulties and challenges that keep the country miserable. That is how rich countries reached the financial level they are right now and it shouldn't be impossible for others, once they follow the same formula.
I can't say about your country specifically, because I don't even know which one it is, but generally poor countries are on this condition because citizens are hostile to each other, try to take advantage of their countrymen (and foreigners), and consequently put people of this same character and behavior at leadership positions. And the minority who have principles and values are put aside from the society, because that is not the majority's lifestyle.
About OP's idea, I think stablecoins can partially help to ease the poverty issue, because with access to a strong fiat currency like dollar for a fair exchange fee price, these people can at least avoid high inflationary local currencies. Before stablecoins, to acquire dollar we had to go physical exchanges houses where the official rates displayed on the TV news and internet weren't respected by the exchanges. Let's say if 1$ was equal to 3 units of my local currency officially, at exchanges I would have to pay 5 units of my currency for 1$. This way only the rich had access to dollar for travelling, touristic reasons, while the average citizens had to stick themselves to national currency only, like a castaway restricted to a tiny island surrounded by sharks (government) which prevented him from going to a closer ship for confort, help and rescue.
