It appears we have a novel financial product on offer around here: "Imgcoin"; While the IMGFLIP_BANK will not prohibit citizens from purchasing as much Imgcoin as they wish, potential investors are advised that in order to convert your Imgcoins back into PRESIDENTS cash, Imgcoin will need Congress's approval and official recognition.
