the problem is that most of the things we read online are not what people really expect to happen. what we read is mostly what they wish to happen specially things they post in social media. for example there are a lot of day traders who place a buy order at for example $9500 when price is $9800 and then come online and "predict" price to fall down to $7000 because they want their $9500 buy order to be filled.
what gives you the impression people are doing that? do you think that kind of "manipulation" has an effect?
most analysts/traders are just wrong most of the time. if they were calling $7k, it's more likely they were just affected by recency bias. so in a downtrend, they just expect lower and lower and lower. shorting the bottom, etc. IMO, most price predictions are what people actually expect. this is for 2 reasons:
1. ego. nobody likes posting predictions and getting it wrong. in fact, sometimes it feels more important to be correct than to make money.
2. a lot of analysts on social media are trying to sell signal services. they need correct predictions, not blatantly wrong ones.
