Grifters gonna grift. Since this is human nature and most of people never learn from History, there will be scams forever. Bitcoin being a pristine asset, many will try to take advantage from its success, just like the suits from Wall Street. There will be victims of course. The beautiful thing is that no matter how hard they try, they will never be able to manipulate Bitcoin itself, only the people around it. They can try of course, but it will be fun how they miserably fail.
