According to PANews, Morningstar analyst Dan Romanoff said that although gold is generally considered the best asset to hedge against inflation, Bitcoin may be a more useful inflation hedge, according to the Washington Post. Over the past five years, the price appreciation of Bitcoin and gold has exceeded inflation, and Bitcoin's increase is 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, and he added: "It seems reasonable if Amazon can keep a small portion of its cash in Bitcoin."
