Monero is so cool. But many people think that it's used for illegal transactions, they are all focused on just the negative things and not all the good things that can be achieved by using Monero. It might be used on the dark market for example, since it is private and people can't really see were the money came from or where it is going, but there are so many other markets that can be served exept the dark market. Illicit activities in currently the main market of Monero, and it's what it is holding back from more adoption. BTC is kinda private too but at least there is some sort of transparency that everyone likes to see.. for example were the coin is going where it came form etc. Monero doesn't offer that and that's the reason it attracts the "bad guys".
