This is very clear that warren buffet wanted to influence the price to make it more cheaper for he can buy it in a very low price, warren Buffett is a crypto enthusiast and there is no simple reason for making negative comment for btc except buying more in dip. I believe that he wanted to buy more on dip that is why he also wanted the bitcoin to drop down deeper.
I am not believe this that buffet only want to make bitcoin cheap for him to buy many of it. He has not spoke good of bitcoin all the time he has opportunity to do that in public places. He don't like it that people can get rich with just hodling few bitcoin in the wallet and the next time lambo
He wants more detail work where you follow protocol, bureaucracy and results is got with such variation. Or you may work under his company doing the 8-5 nature of job but he can wake up now because that time is almost going into history.
