they are all haters of bitcoin, maybe when they say bitcoin is a scam or ponzi scheme they do not know about bitcoin, i think you can tell them about bitcoin, how does it work, why bitcoin? and anything else, but if they announce bad news about bitcoin like a tool for criminals, I think they are bitcoin haters and want to make bitcoin die, or maybe they want to make bitcoin prices down so they can buy more bitcoin when the price is low, back again our own individual to be smarter again facing the situation as it is today.
