What does a stick do to you? It could be  anything depending upon what purpose it is used for. It could be violent, as to whipped an erring child or be as useful as a person's additional hands or legs. This is what bitcoin is. While it can do good it can also be used to create scams. I just hope people realize how useful it is in the real world and use it not only for doing a scam. Certainly without any doubt bitcoin is not a scam,  some people are.
