sometimes in media show only negative news about bitcoin and people tend to believe in the news. because people dont know bitcoin and the people who heard of it dont trust bitcoin. I think with a great promotion will make people curious with bitcoin and began to find out about it
Not all news in media are real, Sometimes they are paid by the powerful or rich people so if they don't want bitcoin to get popular they will paid medias to ban it or make a negative news about it, like here in the philippines the media are paid and many corruptions happened.
I'd say that most of the news is biased and some portion of it paid. Bitcoin at the start got a lot of bad reputation because of its anonymity and the dark web. In any case, everyone initially tries to reject any new ideas and try to question them hard. Bitcoin went through that as well. Now it is slowly catching headlines in good light and slowly big companies will get involved as well.
