Many exchange services work with electronic wallets, where ETH funds are received and then processed through an offline or online procedure for issuing hryvnia. The double verification function is increasingly being connected, thanks to which the user receives a notification about the transit and final confirmation. If an exchange is used, it is important to understand that it does not have the option of directly receiving cash, such transactions occur only through external exchangers, and the risk of error is higher. Therefore, preference is given to specialized exchange points tracked through monitoring.
