2021 was another strong year for cryptocurrency, as assets like Bitcoin and Ethereum were able to build on positive momentum gained at the end of 2020 and hit new all-time highs in 2021. Overall, across all cryptocurrencies Chainalysis tracks, investors around the world realized total gains of $162.7b in 2021, compared to just $32.5b in 2020.
The United States leads by a wide margin at an estimated $47.0 billion in realized cryptocurrency gains, followed by the UK, Germany, Japan, and China.
