I had a similar idea, so I looked up the process for starting a bank. There's a good reason fresh-faced startup VCs can't get into it.

- Extremely high starting capital requirements (10-100 million USD)

- Knowledge on security, finance, and law, means you will be needing an expert team of lawyers, accountants, cryptographers, etc.

- An actual location and strictly controlled building to keep the physical money.

There are a lot more requirements but the first 3 make it almost impossible for a lay-man to start their own bank.
