Will the Taliban do that? I don't think so, how they'll get funded with bitcoin? They're now like as a hermit kingdom when the country has been taken over by them.
I think that there is real potential there.
Even though the Taliban will certainly never endorse the currency officially, I think that with the broken fiat system there it will be inevitable that people will seek solutions.
One of the most obvious solutions right now is clearly bitcoin. They will likely not want to transact with USD given their animosity.
I don't think that they'll turn into that solution as much as possible with the current time. They're now the government and I think they'll do something within their powers but without touching the bitcoin market on their country.
