The actor pattern is used quite a bit in the functional world (Akka is pretty popular in the Scala ecosystem). It's just a design pattern that lends itself well to distributed applications with complex communication structure like some microservice systems. Some people use it to represent graph-like data structures with nodes that update themselves based on their neighborhood, though that's kind of gimmicky. There's no connection at all (that I'm aware of) to crypto or fintech scams, and I guess it doesn't hurt to have a look at the actor pattern if you're in a functional language; always good to know what tools exist.
