It is very important that we do our own research and not believe in anything we see or read on the internet right away. However, these days it is getting a bit harder and harder to determine authentic news from the fake ones.
In crypto, I would be extremely skeptical of basing your trading behavior on news of what other investors (whales) are doing. Certainly it could be fake news to begin with, but trying to follow the herd and being a momentum player has failed many a trader.
At least in the stock market business news is pretty easy to verify the accuracy of. With crypto news coming from sites that look like they value rumor just as much as real news, I'd be very uncomfortable using that kind of reporting as the basis of my trading strategy.
I don't hear much about contrarian investing around here. Seems like everyone is trying to be momentum traders instead of following the "buy low/sell high" strategy. Buying low sometimes entails buying coins that are unpopular at the moment, and my impression is that many crypto traders are extremely fearful of doing so--they're instead chasing what they think the next big thing is or buy what they think everyone else is buying. It's no wonder so many crypto traders lose money.
