They claim, for example, that Bitcoin addresses the problem of the world's unbanked population. Well, I should also say many of the unbanked are technologically-illiterate, poor, beyond the reach of electricity, don't have access to internet, and so on.
I appreciate that point of view, but that's not what I think of when I think of addressing the unbanked. Bitcoin overcomes the issues with banks, not the issues with entire infrastructure of the country. If you have terrible credit and have been turned down by a bank, bitcoin addresses that. If you have no ID and so can't open a bank account, bitcoin addresses that. If you have no fixed address and can't open a bank account, bitcoin addresses that too.
Yes, of course. That's selective, but that's all right. In the same manner that when Visa claims to be a network working for
everyone, that shouldn't be construed literally either. It is also selective. The
everyone there obviously refers only to those whom it is applicable, the banked. Although, right now, things are apparently getting better with Visa-supported crypto wallets.
Anyway, banks are already addressing banking issues themselves such as lack of a valid ID or a permanent address.
