bitcoin in my country is not so well known because not many people who know and understand the workings of bitcoin
I don't think people need to know the "in's and out's" of bitcoin in order for it to be widely used and accepted as something that is positive for the world. All they need is the general benefits of bitcoin.
The OP is right though, many things have happened over the years that has caused bitcoin to get somewhat of a bad rep, as of the last ~year or so, the flow of bad rep news is somewhat slowing down
