I will answer your question but I will also point out to you, a new procedure that we all must adopt, according to superior directives, in order to encourage all those interested in knowing more and better about this gigantic project. So, what you can do through the Exchange is to give a sales order or a purchase order. Regardless of the current quote, you can say that you want to sell a certain number of coins, when the quote reaches a certain value. For example: I sell 100 YtC's when the price reaches US $ 5,00 or, I buy 100 YtC's when the price falls down to US $ 0,14. The Exchange will find someone interested in buying and the match will take place.
The directive coming from the general coordinator of the cooperative, invites you to: 1) - Enter www.gdc.coop;
2) - Choose YtC; 3) - Now, "test your knowledge". You will find all the answers to your questions. If by any chance, you don't find the right answer, then ask your Broker, your G.M. or post it here on the forum.
