Not to discredit your question which is important in context... I feel like Both of them overlap and there are some really, really interesting problems in finance which most people don't have the balls to solve. There's a reason fintech startups are few and far between in comparison to the rest.

I was asking because I used to work in a bank, participated in two fintech startups, and have returned to banking due to circumstances with my family. I was going to target my advice based on the answer; however, after thinking this over some more, my advice would be the same for either answer. Stay in banking. There are a lot of problems in banking that need to be solved, and I think being on the inside of the bank gives one the best chance at solving those problems.
