Once people don't support on an innovation or any newly introduced technology, then they begin to raised a counter attack against such in other to discourage others from going for it, because they believed that painting them with fake news will go a big way in tarnishing on their image and reputation the world could have expected form them, there are many reasons behind why fake news is coming, some are doing this out of jealousy, because they envy on what others have achieved.
Like what's happening to Bitcoin back then, there are countless of fake information spreading across the internet to fud BTC but a lot of enthusiasts prove that BTC is the goat. Like when people who have traditional mindsets spread false information to avoid it because it ruins their business but right now looks what's happening, people are now sticking to BTC and taking advantage of the potential profits.
This is a cruel world, if you're behind and doesn't have any idea or knowledge on the space you we're at, you'll probably going to be those people who just believes what big names said. This is the power of false information, it can fool and manipulate everyone, so we need to stand out by learning and having our own understanding to each thing by studying it.
