~ many traders in remote villages worldwide prefer Bitcoin as a better means than traditional banks because it only requires them to have phones connected to the Internet.
Not sure that's true. Almost certain it's not. I've worked and lived in many of the most remote villages in the world. Where it's not smartphones but regular phones that people have, if at all. In these places, it's GPRS you can hope for at best, so SMS money payment/transfers work best. 0 fees and the ability to do micro transactions.
Talking about 0.1 cent payments for a sachet of iodised salt, or shampoo, or chlorine. 0.01 cents for matches. These aren't even amounts you could pay with Bitcoin, as you'd need to send 1 satoshi or even sub-satoshi payments with LN.
I'm pro Bitcoin. Love it. But I also live in reality. And a big part of the world still lives in a removed reality where Bitcoin is not (yet) practical.
