Buffett says it will issue a "Warren currency" after death, but will never hold cryptocurrency

Billionaire Buffett once again reiterated his aversion to cryptocurrencies in an interview with CNBC on Monday, saying that cryptocurrencies are basically worthless and produce nothing. I don't hold any cryptocurrency and never will. However, Buffett revealed that he would release a "Warren currency" under his own name after his death. Buffett, 89, has always been a critic of cryptocurrencies, and previously he described Bitcoin as a "real bubble" and "square of rat poison."
