What cryptocurrency exchange platforms with low fees do you know? ?

Recently I exchanged several bitcoins through a new platform and it attracted me because the commission for the first transaction is zero - this is a big plus when you transfer a large amount of money. The exchange process turned out to be fast and without hidden commissions, and the money arrived within half an hour. Plus, the service works in 180 countries, so it turned out to be very convenient for international transactions. If you need a reliable and fast crypto exchange, I will leave a link to the page here - an excellent choice.
