I recently moved some assets out of JPM Chase and into Robinhood precisely for innovation. Trying to use the JPMC brokerage was clunky. Fintech brings innovation while still using the stodgy old banks on the backend. It turns out that Robinhood spending accounts are Chase accounts. So, I didn't really change banks, just front ends like on Hive.
With X, I'm curious if their system will just be a front end or end to end banking.
