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.
What actually strengthen the market is the negative news, I don't really call everything as news as some are just article based on the writers opinion, some speculation and some FUD by investors in the space. We have to be matured and smart in order to absorb all these without panic.
