In Africa, we have plenty of Hawala men, people willing to do currency trading, there are also a host of informal shops that are willing to sell ou just about anything like your news agents, you can buy Bitcoin from them too, through vouchers that can be exchanged with Azteco, they are none the wiser they're just selling you vouchers which most people use to fund betting websites or buy airtime or data

Your max purchase is around $150

Getting into Bitcoin isn't all that hard, getting out/purchasing with it is harder, theres no way to really turn that bitcoin into stuff you want sure you can use vouchers like bitrefil but again friction with having another payment method

Currently my view is P2P markets will grow with stablecoin adoption, its the only thing that settles as fast as Bitcoin and issuers of stablecoins are pushing merchants to adopt it, and people are informally adopting it all over Africa.
