You must first wait for the release of the Libra coin, and only then evaluate the possibilities of non-acquisition. Since Libra will have serious problems with walking in European countries, it is most likely that there will be similar difficulties with walking in the USA, Libra will not be difficult to purchase for African countries.
As for the price of the Libra coin, it will not be too expensive, since it should have approximately the average price value of those ordinary currencies with which it will be provided. Therefore, it should be thousands of times cheaper for the price of bitcoin and it does not have the opportunity to grow in price, since it will be a stable coin.
