the possibility of that direction seems very reasonable, but is it possible for third world countries whose financial systems are still not well integrated, for example poor countries with digital currency needs are still very few and still need conventional exchange tools, because there are still many traditional markets that only accept direct exchange without any digital technology in it, and there are still very many countries with such conditions, so it still seems to take a long time, but for developing countries it is very likely to be realized because the market system is already online, buying and selling already between countries, so they need a fast exchange tool and do not require complicated regulations, so in my opinion bitcoin may be a medium of exchange throughout the next ten years but only for countries whose financial systems have advanced.
