Without a doubt, the crypto market flourished in 2021. Over the past year, the total market cap of cryptocurrencies exceeded $3 trillion. As the first Bitcoin ETF futures in the United States started trading, Bitcoin has been increasingly adopted as part of mainstream portfolios. Driven by the NFT boom, cryptos have captured public attention, creating strong market excitement. Many crypto big-shots, including Ryan Selkis, founder of the well-known research institute Messari, believed that the BTC price would hit $100,000 by the end of 2021.
