You can receive payment on the Ethereum network (L1) or on Zksync Era (L2). If you have not opted for Zksync Era you receive payments on the Ethereum network. Last month the fees were above $60, so to get paid you would have had to earn over $60.
If you choose Zksync Era (L2) you will immediately have the amount earned, but it will be on a secondary network and to cash in you will have to move it to L1 and pay the related fees. L2 is more laborious. However, after 9 months you collect the right amount and after 15 months you get back half of the amount withheld
