I think people who say bitcoin is bad just don't really know what bitcoin is. They heard some negative news in mass media and think it is some kind of scam or financial pyramid. But when people will learn about bitcoin more they will understand how great this technology is.
agree. there is a lot of negative news about bitcoin circulating in the mass media and besides that those who don't understand bitcoin only hear one ear without seeing what the advantages of this technology are. I think some of those who consider bitcoin bad need real enlightenment that bitcoin is actually not bad.
