There had been a number of online scam which run away with investors money. Seeing the huge returns involved with Bitcoins, it also looks suspicious to many. As a result, media tries to make people aware about Bitcoins as well. Only thing is that they need to do more research before coming up with the news as it affects the prices.
Actually, Media only uses Headlines that can easily be sold. Wouldn't it be more sellable if you use a headline "Bitcoin a Scam" than to "The LN and whats the use of it." They tend to use negative news of bitcoin/Crypto because it generates more clicks for the readers.
