To conduct exchange operations in the GrandChange service, registration on the exchanger"s website is not required. After the first exchange, the service will register the user automatically and send information about this to the e-mail specified when forming the exchange request.

In the future, if the user plans to use the service constantly and accumulate a discount (you can read about the cumulative discount system here) for the exchange, the user must be authorized. That is why registration in the GrandChange service is useful and profitable.
