The exchange rate is determined based on the market value of Bitcoin, the blockchain fee, and the selected payout method. Before sending BTC, it's helpful to monitor quotes, compare the exchange data, and confirm the final commission percentage. GroshX offers a favorable rate and displays the amount that will be credited after the transaction is completed. In addition to euros, clients can choose UAH, bank transfers, hryvnia, cash, or other available payment methods. If cash is required, the terms of payment are agreed upon before the cryptocurrency transfer, so the client knows the location, time, and payment method in advance. This approach makes the exchange process more transparent and helps avoid errors when entering information.
