Anyone claiming that bitcoin is bullish at this point is severely jumping the gun. The market has been bearish for nearly 1 whole year now and nothing short of a big bullish movement spanning 1 - 2 months is going to convince a large portion of people otherwise. So many people called the bottom at 6k and they were wrong, it could be true for 3k as well.
People are easily convinced that the price will either go up a lot or down a lot. It all depends on what the price is doing right now. The flow of the market is the main driver when it comes to the sentiment in the market.
If we tank to $3500 people will dig up articles stating that $1500 is near. If we reach $4000 people speculate about the next bull run and the potential high that comes with it. It has always been like this.
As for the $6000 mark, yeah, I was expecting the worst due to how bullish people were at that point, and the market did the opposite. People have only themselves to blame for this. You don't go against the market, period.
