M Bunq is an internet bank. Unfortunately, bunq doesn't have the physical infrastructure of ATMs, that traditional banks have, to provide cash deposits.
Besides, bunq is a bank from the Netherlands where people hardly use cash. The only option to deposit cash in the Netherlands is to ask a friend or family member with an account at, for example, Rabobank, ING or ABN AMRO, so they can deposit the money for you and transfer it to your bunq account.
