everyone has the right to make predictions but this prediction must make sense, because predictions are made to be trusted by many people. what is your reason for saying the price of bitcoin will fall to $ 3k? Your predictions are very ridiculous.
This is just his personal speculation without any factual possible proofs and claims to support that theory, he just drops the word $3k for December next year, possible but you must back it with claims to make it believable that it will drop to $3k like nothing next year? worst drops were happening this year but we have the bottom of $6k and that's it the price did not pass through 5k back then.
