There are a lot of people who are still against crypto currencies and Bitcoin particular. There has been a lot of scams and fear has spread among the people. Those populations are scared now, and they are not trying to invest, they are just scared and they are trying to do all in their power to spread a word that Bitcoin is zero worth, that all this is crap, and so on. There will always be people who are trying it to ruin the whole thing for everyone else. Why should all people enjoy earning the big buck, when big whales want it all for themselves.
Actually we can't force people to accept bitcoin especially when they don't have any idea the real goodness that this currency could brought to his/her life. This is such a good example that not all things should be explained briefly if people would not wanted to believe it but instead show it to people that this is such a good thing to try on.
