I kinda agree with his prediction (despite the fact that he is a "bear" and he is dying to see a lower bitcoin price).The true bottom will be around 2-3K USD and any new ATH will happen after the next 2020 halving.
It takes a lot of time to build some new hype around bitcoin.The market is insecure and the fear dominates over the greed.
For everyone's information, he is not a
bear. He is one of the most maximalist of all the bitcoin maximalists in the cryptospace. For him, any cryptocoin that is not a bitcoin is a scam hehehe. He trades both directions of the market, however.
