I just don't know how crazy they are when it comes to predicting these numbers in that specific day, month or year. Even John McAfee's prediction of $1 million dollars per BTC by the end of 2020 may be impossible as he is now "under pressure" of eating his d*ck live on TV!
Not even halving would guarantee the claims of analysts like him that Bitcoin would "moon" for real.
Everyone like to make a prediction and earn money doing so because these predictions are click baits to attract crypto investors and they are making money with these kind of predictions, i would be surprised if the price crosses $50k let alone $80k . There is a lot of resistance to break to reach the current all time high valuation and i have no idea when that will happen let alone these huge predictions
