In case you intentionally left out the /s at the end of your comment...

You'd be surprised how advanced the banking systems are in some 3rd world countries. In many cases the banks skipped over a lot of the legacy cruft that 1st world countries are struggling to get rid of now.

Also, in countries where the banking system or currency is falling apart, they use USD cash. Zimbabwe is doing this, Argentina is doing this, I'm sure more places also do this.

Also also, often where you have crumbling banking or currency, you also have crumbling internet and/or electricity infrastructure. Nobody is sitting on an upturned milk crate in their dilapidated corrugated iron shack in the middle of a slum fucking trading bitcoin on Coinbase so that they can buy bread.

Bitcoin is 99% used as a speculative investment instrument and as a means to participate in illicit markets (drugs etc). There is nothing altruistic or democratising about it.

the certainty of this post is its undoing. Someone once relayed this story .. while speaking between two intelligent but not expert adults, about the "size of the Internet" .. one said .. the Internet is so big, that there are whole social groups online, for example a popular multi-player game in Korea, that you have never heard of.. yet there are hundreds of thousands of active participants in this thing that you have never heard of.. that is how big the Internet is..

So wrt. this Bitcoin.. one armchair Admiral is going to pronounce that "electronic cryptographic money exchange Only Does This (list of things that are obnoxious).

It is parochial.. the definition of uninformed.. people who are directly involved don't know all the things that are being done with Bitcoin.. dismiss simplistic portrayals

I'd bet the biggest use case is scamming/extorting people. It has been the fastest growing use case, it must move more money than all other use cases combined.
