Coinbase screwed up GYEN, and issued people a hundred times whatever they had paid for, those that were smart transferred it out to a wallet and were able to keep it, those that aren't smart, like me, tried to sell it only to have it failed the sale, and then sell for the actual price, shortly after they froze the accounts of everybody that held GYEN, they just this evening released the hold on those accounts, but the GYEN assets are still frozen
