PANews reported on December 22 that according to the Washington Post, Morningstar analyst Dan Romanoff said that although gold is generally considered the most suitable asset to hedge against inflation, Bitcoin may be a more useful inflation hedge tool. Over the past five years, the price appreciation of Bitcoin and gold has exceeded inflation, and the increase in Bitcoin has been relatively much larger. Dan Romanoff believes that although there is not much historical data on the performance of cryptocurrencies in different economic cycles, a small investment in Bitcoin can be made. He added: "It seems reasonable if Amazon can keep a small portion of its cash in Bitcoin."
