This is from an 18 minute video titled "Warren Buffett on the 2008 Crisis" where he is interviewed by Andrew Ross Sorkin of CNBC about the 2008 financial crisis when home prices collapsed on a widespread basis. If someone could post the link below, I'd appreciate it.
Sorkin asks Buffett to look forward and what he is concerned about in the future. This is Buffett's classic response (at the 15:42 mark):
"Asset appreciation draws in people who don't really know anything about the asset. And people start being interested in something because it's going up, not because they understand or anything else. The guy next door who they know is dumber than they are is getting rich and they aren't and their spouse is saying 'Can't you figure it out too?' It is so contagious."
What asset is going up right now that this quote could refer to? What about bitcoin...
