2021 was an impressive year for crypto as the market, led by Bitcoin, expanded to a market cap of roughly $3 trillion, up from $800 billion at the start of the year. Bitcoin itself was able to maintain a market capitalization of over $1 trillion for several months and stands at approximately $1.1 trillion at the time of writing. While its price action throughout the year was well documented by the media, its adoption as an inflation hedge and as a currency were overlooked.
