It is a good idea to take into account all factors affecting a market, even if some of that news might be influenced or biased or has some agenda - it might lead to some opportunities that might arise that may not otherwise have been there. But yes everything does need to be taken with a grain of salt.
We really can't deny the fact that there are some opportunities that are opening afer those news.
But I'm against of spreading fake and false news, this really leads the market into a situation where it shouldn't be. There's a recent the same thing happened about Goldman Sach's news that they stated news spreading about them opening a crypto trading desk were fake.
