All this data is just a lagging indicator. If you were around those Reddit posts back in Dec 2018 when we hit $3100 people were saying that BTC will hit 3 digits sometime in the next few months. Same with the June 2019 bull market, people were saying that it will hit a New ATH before it goes to $100K

Right now people are saying we will hit $5000. And there was a slight rally since then. So based on this data you can't really trade off it because people start complaining about BTC after it falls and people praise BTC after it rallies, so unless you got some time machine it's useless reading those posts.

That's why you need to learn to trade on your own. Because that way you can't blame other people for your losses.
