Almost every criticism here applies to all cryptostocks, and there are hundreds of such hybrid altcoins. So, RhinoCoin may or may not be a scam, but you can't fault it for the issues all cryptostocks have. Any cryptostock has a lot of risk, and may have legal issues in the US, and does not have SEC approved type financial records, and the vast majority don't have projected financials or all the other things that normal stocks and investments have. That is just the nature of the game.
