There are a lot of use cases for bitcoin. For westerns like (presumably) us the main use case right now is transferring value on a network nobody controls, nobody can shut down, nobody can censor you, achieve final settlement in 10 minutes, all for extremely cheap.
But for many places around the world the use case is even more obvious. Many people around the world have a big money problem. Their money inflates at a rapid pace, their country has capital controls so you can’t even move the money out if you wanted to, and in many cases it’s very difficult to transfer said money into US dollars or other assets that will not depreciate so rapidly.
For these people, and it’s not a small group, bitcoin is legit a life raft. It’s hard to understand how people still don’t get this.
