This cryptodouble has been online for a few months now and appears to be paying its investors. In fact a couple of people I know on the internet actually invested some, for example below 100k Doge was invested yesterday. Let say if they pay,  you can check live. https://dogechain.info/tx/479545e7dc1a9ccc4866d4626fd57f9035c6958381c1581fba699e3608f95216 http://cryptodouble.com/?ref=SLpE2
