When you register, you may specify your location. You also provide details of the payment you want to receive in the order request. The system will show you counter-offers that match your specification. For example, you are from Kenya and want to receive fiat proceeds to the banking card. In this case there will be a list of buyers from your region with the opposite need (bid or offer). You will see prices and volumes available in local currency trasferable card-to-card in local banks.

Many thanks for you quick and valuable reply. Are there any restrictions or limitation for certain countries?

[/quote]There are no constraints. It depends on set of options in each country. For example, you may use PayPal  everywhere. Using private chats and dashboards you may discuss any form of exchange, including banking wires and cash transactions.
