my neighbor ask about trading, "can you make and withdraw money from trading?" and i said, yes i can. but he still unbelieve and ask more and more the same question. so i explain basic of trading.
actually they just less information about bitcoin, what they know is negative news, so they called it scam.
This is the reality, rather than the good the bad news easily reaches the common people who keeps on running for their daily life. Bitcoin is nothing an exception. Very few understand in the right way and explain good about the good and true value of the cryptocurrency.
Another thing, some people without any proper understanding used to get into bitcoin usage and with their mistake they couldn't make big earning and might have experience big loss. This creates a negative thinking in their mind and the same will be spread, and these people never realize their mistake.
