I think there will definitely be no reason to convert to fiat.
Bitcoin is not for alleviating poverty because the path is different for each financial capability possessed by groups of people who use Bitcoin as an investment asset.
With the rapid development of information about Bitcoin all over the world with the knowledge gained from reading about the direction and benefits of Bitcoin, various groups of people can use Bitcoin as a means to convert fiat into Bitcoin in the sense of saving for their hard work while working on a real job.
What does the OP mean to be able to improve their economy financially when someone already knows bitcoin and invests in it? But if it is to alleviate poverty then it is the government not bitcoin.
Bitcoin has grown rapidly and now almost the whole world has recognized it (not that it's always public) but we already know how the benefits and how bitcoin works and with the technology that is owned, it would be very natural if more people would use bitcoin as their investment asset to get a high ROI over a long period of time.
