There are so many predictors who predicted that BTC will go to 30K$, 40K$ or even some predicted 50K$ as well. From March to December 18, there are so many posts about the speculation of BTC but all failed. In my research there was only one post which predicted that ETH will go to double figure. Now ETH is in double figure. Believe me that was blind guess because that person that does not give any logic. Account was newbie as well. So you can imagine
Predictions are simply that, mere guesses, not all times blind. Some can research and arrive at suitable price speculation, and yet be wrong.
After the pump of late 2017, everyone had the bullish mindset, and we're predicting Bitcoin climbing to above $250k in the next months.
Only a few calm heads could see through the hype and FOMO and realize it was unsustainable for the long run.
