Buffet is good at doing his research for stocks and has made huge gains at stocks but he is not very good at doing his research for cryptocurrencies, where he absolutely lacks of knowledge. He even wanted to date Justin Sun, CEO of a fraudulent coin called "TRON".
Buffet should stay at his stocks or doing technically detailed research about cryptocurrencies before making conclusions, like he often does. As a Boomer, his focus is clearly outdated like so many conservative Boomers. Cryptocurrency will be a step forwards and everyone who will buy it right now (only good coins) will make good money.
Warren wasn't talking about cryptocurrencies, he prolly might have expressed his disinterestedness in Bitcoin in the past and that's pretty much understandable, but Buffet's current claims about inflation is correct, it's basically there for everyone to see, the policies most governments have taken in the past year or so is definitely going to result in inflation. in my country, prices of everything has gone higher than what it was previously, and I mean for practically every good and service, that's the inflation we're talking about, and it's yet to get to the climax, it's just at it's "milk teeth stage", thus who knows what's coming in a few years.
We're talking about the government printing money for stimulus bonuses, which is prolly the major cause of inflation, but the government were in a state of delimma, covid-19 was a unforseen circumstance that rocked the world, there were little other alternatives to pump money into the economy. I'm not in support of printing excess money just like that, but imo, it was what the government felt they had to do at that moment to sustain the economy from total collapse.
