Is ATOM a bank?

Excuse me, could you clarify something for me? I've been hearing a lot about ATOM recently, and some people seem to be treating it like a bank. But is ATOM really a bank? I'm a bit confused because, in my understanding, banks are institutions that handle deposits, loans, and other financial services. ATOM, on the other hand, seems to be more associated with cryptocurrency and blockchain technology. Could you please explain the difference between ATOM and a traditional bank, and why some people might mistake it for a bank?
