The main point of bitcoin is that you can be your own bank and no third party or bank account is needed. Maybe this is unnecessary for you, but for many others it's not. Some people don't or can't have a bank account and bitcoin is a solution to that. Many people are also treating bitcoin like a speculative asset as well where there's money to be made from trading or even holding it (know as hodling here), but that doesn't come without risk. If none of that interests you then bitcoin might not be for you, but I think everyone should try own a little bit of bitcoin whether it's to hold as a long-term investment or just to be a part of the revolution. What you do with it is entirely up to you though.
