Crypto will never be a viable alternative because there is simply no practical use for them currently, and in countries like Egypt; it’s impossible to resell or even buy crypto.
It’s so frustrating to see people (especially tech bros) constantly glaze over a piece of tech that simply is not accessible for a good chunk of the world, and can introduce risks to people’s lives for simply owning it.
Unless someone out there is ready to create an entirely new payment processor that can function in countries like Egypt, that also have a workaround for people there to own and use crypto, crypto will simply never be a viable alternative for a lot of people.
