Base Use Case - Withdraw
As an attendee of Devcon, I would like to be able to withdraw Colombian Peso (COP) bank notes from an ATM, thus:
INPUT: Token (e.g. a Colombian Peso ERC-20 stablecoin, or other ERC-20, or even ETH), from my wallet.
OUTPUT: Pieces of paper (bank notes)
Stretch Use Case - Deposit
