The technology is not the problem actually. The problem is the one using technology. If people are using these technologies in a good way, then we have nothing to worry about and all will go well. But that is not what happening right now. Some people are too greedy and always wants to take advantage. Those criminals only want to steal and get for their self-interest.
Yes, I agree with you. Bitcoin is not the problem, the problem is the one who uses bitcoin and what are the intention for using it. Many people uses bitcoin to improve their daily living. They want to have a better life by the use of bitcoin. But they have many bad people want to used bitcoin in a bad way. They used bitcoin for their crimes so that they can benefit with it.
