As I can see this thread is showing me that people experience exactly that, they donate in order to use their coins, in order to donate you need to activate the authenticatior (this is my case), in order to trade you need to wait for 3 days, which kind of kills the excitement of getting what you want with that donation. I understand it is a security feature and I appreciate that, however, I might be wrong but can't the authenticator be connected to your purchasing (trade, services etc) via coins, for example, if I want to buy Gold for Coins, in order to confirm it, check your authentication method. Idk, it's not a lot to wait 3 days, sorry for nagging, I m just expressing my mind.
