The price of bitcoin took a dive after Warren Buffett renewed his criticism of the cryptocurrency — even comparing it to rat poison.
Bitcoin had been closing in on $10,000, but it fell nearly 6% Sunday and was down another 2% Monday to just over $9,300.
Buffett, the CEO of Berkshire Hathaway (BRKB), has been a bitcoin bear for years. He has often compared the cryptocurrency to gold, saying that both assets are strictly speculative and don't produce earnings and dividends like stocks do.
