Binance I have used it for 6 months for currency exchange operations and it works well, it is very fast and intuitive, it seems really safe when making withdrawals since it asks for 2FA verification, it is full of custom functions for Latin American countries, specifically For the purchase and sale of Cryptos type person to person it is really very useful especially in Venezuela, where there is an exchange control that limits exchange operations, making access to cryptoactive assets really limited.
