Ask HN: Should we create a Crypto Bank that issues bank notes?

Some people have created "bills" and physical "coins" that actually contain crypto. I haven't seen anyone creating bank notes that are simply backed by a bank that stores the crypto for them. What do you think about the idea?

I believe it could be useful for people in some developing countries. My initial idea is to create a branch in Colombia/Cucuta, oriented to support people from Venezuela crossing the border forth and back.

Pros about such a bank:

- Crypto bank notes enable off-chain transactions with zero cost.

- Bills/notes enable use non-gov backed currency (may fluctuate, but won't have inflation) without requiring internet.

- A "current" crypto bank account also enables you to forget about taking care of the security side of crypto addresses, where it's also easy to move money to an Ethereum address or back to other currencies like colombian pesos or dollars.

What do you think?

PD: I'm based in Europe, but I've been to Colombia.
