"You do not have enough non locked coins to purchase this sale, try again in 72 hours."

About 12h ago I sold my char on warmane trade, I was able to spend coin on DBW, but when I want to spend coins to buy gold I get this message...

I dont understand? How was I able to buy DBW without getting this restriction but I get it when I wanted to buy gold, there was a good offer and now I must wait...

This restriction is for player to player transactions, that is why.

Okay thank you.

To be a bit more specific, it's so stolen Coins can't be forwarded across a chain of multiple accounts by abusing Trade or Gifting, giving time for the legitimate owner to notice and take action. It unfortunately means a minor inconvenience to real users, but that's about the same with everything security-wise.
