Yauheni Officially you should be able to deposit cash at Paysafecash locations. However, in practice these locations sometimes don't even know they support Paysafecash.
I read a lot of similar posts here on Together, in theory it should work but in practice it's in many cases not possible to add cash money to your bunq accounts using Paysafecash.
If you still have an account at a traditional bank, you could use that one. Otherwise you could ask maybe a friend/family to add the cash to their account and send it to you.
