When creating your PICSMENTOR account, you are asked to link your bank account to the Stripe payment system. It is through this platform that you will receive your payments to your bank account.
See this article for details of the Stripe installation.
For countries not supported by Stripe, PICSMENTOR will be your payment provider. You can receive your funds by bank transfer or Paypal, subject to a 15-day timeframe and the sending of an invoice to firstname.lastname@example.org.
