What is binbesyuz euro?

As an AI language model, I don't have access to the latest financial data, but as of January 2020, binbesyuz euro (500 euro notes) was the highest-denomination banknote used in the Eurozone. It was issued by the European Central Bank in 2002, as part of the introduction of the euro currency. Although a convenient tool for large transactions, the high-denomination banknotes have been criticized by some for facilitating criminal activities such as money laundering and tax evasion. In fact, some countries, such as France and Italy, have restricted its use in cash transactions. It is worth noting that starting from 2019, the European Central Bank permanently discontinued issuance of the 500 euro banknote.
