Big news! It seems that he has identified the bottom and is confident that a recovery is under way. Berkshire now has a bitcoin department which is why the price pumped this past week. Go get some!
I googled and couldn't find any such news. Can you please share an authentic link for our information.
In my view the success of BTC lies in mass adoption in every country and it doesn't matter that giants like Warren join the crypto community or not. Since it's not easy to manipulate the crypto market like equity and commodity market, I don't see big giants coming to crypto market.
