Marc Andreessen quoted Warren Buffett this week. The legendary venture capitalist blasted the investor’s bitcoin views in 2014.

Marc Andreessen revealed in a that his favorite piece of investing advice is: "Put all of your eggs in one basket and watch that basket closely." The legendary venture capitalist attributed that quote to Warren Buffett (it appears to to Andrew Carnegie in 1885), which is striking as Andreessen has blasted the Berkshire Hathaway CEO in the past, and Buffett doesn't exactly follow that mantra. Buffett in 2014, labeling it a "mirage" and describing the idea that it's inherently valuable as "just a joke." He compared the cryptocurrency to a check or money order, dismissing it as just another method of transmitting money. Andreessen, the cofounder of Andreessen Horowitz, shrugged off Buffett's bitcoin critique as ignorant at a CoinSummit event that year. "The historical track record of old white men who don't understand technology crapping on new technology is at 100%," he said, . The venture capitalist elaborated on Twitter shortly afterward. He described Buffett as a "personal hero" of his and a "world-class expert in many areas," , but he didn't value the Berkshire chief's uninformed opinion of bitcoin. "I know nothing about railroads," he added, likely referring to Berkshire's ownership of the BNSF Railway. "Correspondingly have no view."
