Buying cryptocurrency on Deepcoin with fiat money is a tricky process. Technically, this is possible, through one of the two fiat on-ramps available on the exchange - Simplex, and Banxa. However, as of writing this, these fiat on-ramps are currently disabled. Furthermore, if you were to purchase crypto with fiat, through either one of these platforms, you would need to pass relevant KYC verification processes.
