The first way is to use an exchanger that specializes in exchanging cryptocurrency for fiat. Such exchange services provide the ability to send Tether USDT ERC20 to the specified wallet address, after which the client receives cash PLN at one of the offline points or through a partner bank. Many platforms work with mandatory identification, but some offer more anonymous methods, especially for small amounts. There are also multifunctional exchanges that offer the sale of USDT with the subsequent withdrawal of PLN through bank transfers and cash desks. However, such platforms require mandatory registration, account verification, and often a significant commission.
