Say you want to move $ from service A to C, before Bitcoin it was not possible without a bank intermediary (B). There is processing time, high fees, business hours, etc.. So you’re handholding the process A to B then B to C.

With crypto I can move money directly A to C at 4am on a weekend, any amount, without talking to anyone for a tiny fee.

Or if I want to move it into my wallet and hold it personally I can do that do. Before Bitcoin that was literally impossible without physically walking into a bank.
