Why are addresses in hexadecimal?

Why is hexadecimal used instead of binary?

Why is hex used for memory?
The hexadecimal system is commonly used by programmers to describe locations in memory because it can represent every byte (i.e., eight bits) as two consecutive hexadecimal digits instead of the eight digits that would be required by binary (i.e., base 2) numbers and the three digits that would be required with decimal ...

Do capital letters matter in crypto address?
