It's understandable that people are being scammed off their btc since it's pretty new and some investors dont really understand it. Ive met scammers who claimed they could double my money by investing it in bitcoin through them. It's understandable that after doing a quick google about btc and how much it has risen in price that people would fall for it.
Sorry, but it's not understandable at all. If people think this is a market where money grows on trees, they will definitely get scammed at some point. It's common sense that when you are being offered a deal involving high returns, that you automatically skip it. If someone is offering you high returns on your investment, don't you think about how that specific person is doing it? And why he would need capital from others to do so? If that person was really able to book such insane returns, he wouldn't share his neat little money making trick, but strictly keep it to himself. Whether it concerns people directly or investment sites telling people they can earn a lot, it's a scam by default. Quite often you hear them saying that they do it to help people earn money....
