An exchanger (exchange) is a service that allows one form of money to be exchanged for another. In the field of cryptocurrencies, exchangers are most often used to convert crypto assets into fiat money (ordinary national currencies) and back, as well as to exchange one cryptocurrency for another.

Most often these are centralized venues: the user sends funds to the service, which carries out the exchange at the current rate and delivers the result to the specified details. The convenience of such services lies in the simplicity and speed of operations, but they require trust in the operator, which manages the client's funds during the exchange.

What to pay attention to

• The reputation and length of operation of the service, user reviews.
• Transparency of the rate and the amount of the fee.
• Security measures and rules, including verification requirements.

It is important to distinguish simple exchangers from full-fledged cryptocurrency exchanges: exchanges operate a market order book and trading between users, whereas an exchanger offers an exchange at a pre-announced rate.
