Several times I have seen ICO coins been sold at really high prices on exchanges, however I see this happening before they coins are even possible to deposit to an exchange. How is this possible? For example right now Zrcoin is being traded on HITBTC, but I can't deposit my coins that I got in the ICO because on the deposit page there is a message: "Please note that ZRC is an IOU for future issued token. Until the blockchain is released withdrawals and deposits are unavailable. Please accept our apologies for the inconvenience."
How can it be traded when it is not possible to deposit the coin?
