Berkshire Hathaway vice chairman Charlie Munger has long been critical of bitcoin and other cryptocurrencies. Earlier this year, he referred to it as being akin to a "venereal disease."
The 98-year-old isn't about to change his stripes now. He appeared to take a knock at Fidelity and other investment companies that plan to let people buy bitcoin for their 401(k) accounts.
Munger said that if an investment advisor wants you to put retirement money in bitcoin, "Just say no."
Munger also took a jab at online trading platform Robinhood (HOOD) and its recent struggles. He said the "unraveling" in the company's stock price is an example of "some justice," adding that the short-term oriented, gambling-like attitude to investing that it promoted was "disgusting."
Buffett attacked Robinhood at last year's annual meeting, saying that the company was “a very significant part of the casino aspect” of the market. Robinhood fought back, saying in a statement that "adversaries of this future and of change are usually those who’ve enjoyed plentiful privileges in the past and who don’t want these privileges disrupted." The statement, which also noted that the "criticisms are unfortunate," did not mention Buffett or Munger by name.
