yeah I believe he doesn't even invest in any tech companies. So naturally something like bitcoin is far too much risk. But unfortunately he has a large following of people who respect his opinion and will never give bitcoin a second look because of his advice.
Warrent Buffet is an old fashion investor. To a certain extent he can predict what kind of growth his investments in traditional companies will realize. Bitcoin is something even the best investment guru can't predict right. It's either a wrong prediction, or a good one. 50% chance.
The current market cap of Bitcoin allows him to take a significant share in Bitcoin if he invests (for him) a relatively low amount of around $50 to $100 million in Bitcoin.
Look at him, the old man should stop worrying about investments and stuff. He needs to enjoy life and burn through his wealth by visiting hookers. What is life worth if you don't enjoy it with the wealth you have earned. These wealthy people are always looking for more. $40 billion must be $50 billion. After a while $50 billion must be $60 billion, and so on.
