2. It's a ponzi scheme/ tulip bubble/ some other kind of scam or shenanigans.
This is one of the most common replies you will get when you tell someone about bitcoins and he do not know about the bitcoin and crypto. He might have got the wrong knowledge from others that bitcoin is fake and ponzi and this is feed in his mind and he never cares to research about it himself.
This kind of thing will always exist, because several news stations are engineered for it. They already have a scheme to spread such fear, and those who read it will believe what they preach. But if we show and point out that it's all bullshit I think they will understand better, although there are definitely people who stand by their point of view. We don't need to think about such things, because of their own natural loss.
