Many people do not know that trading is a game of skills and most times jump into it without thinking that it takes them time to make money from their day job. Some even involved in hard labour and most times lose those money with a fantasy that there are going to make serious profit from buy coins at the wrong time. You should buy when bitcoin is low and sell when it is high but most traders do the opposite and lose their hard earned money.
The root of this is the same BTC users. LOTS of them just promote the technology as a "get quick rich scheme". And since it can actually be profitable, newbies only get because of the financial benefit, without understanding the true power that is behind the technology.
