Re: How can people in extremely poor countries custody their Bitcoin?
I don't know in which country people regularly earn as low as 1$ per day, I mean the majority of the population, but if there are such countries, then I'm sure that in such countries people do not have access to computers, smartphones and laptops. They won't also have access to the internet because it's expensive and might cost them 1 week of their salary. Also, with the tech and internet, you have to consider electricity, which isn't cheap anywhere besides Russia. There is simply no way for such a low earner to have access to Bitcoin or informational technologies, so Bitcoin is not really for them.
Btw in the extreme cases, if their friends or close people have access to Bitcoin and these people need to make a transaction, they can use Lightning Network or use an alternative currency like Ripple or Litecoin.
$1/day may sound extreme, but the truth is that the poorest countries in the world in Africa like South Sudan, Central African Republic or Democratic Republic of Congo...According to the World Bank, these are countries with an average income of $2-$3/day and this figure accounts for 60-80% of the population. Likewise, only 3%-10% of people in those countries have access to the Internet. That's the main reason why the adoption of bitcoin as legal tender in the Central African Republic quickly failed just a few months later in 2021.
You are right, bitcoin is not for them.
