Adoption by Institutional Investors and Corporations
In 2021, interest in cryptocurrency among institutional investors and corporations grew significantly, becoming one of the key drivers behind the rise in the price of Bitcoin. Early in the year, the combined demand from institutions and retail investors pushed the price of Bitcoin above $40,000 for the first time on January 8.One of the most notable events was Tesla’s announcement in February 2021 that it had purchased $1.5 billion worth of Bitcoin and, at one point, indicated it would accept Bitcoin as payment—news that pushed the price of Bitcoin above $44,000. Since then, numerous companies and funds, including MicroStrategy, have also incorporated Bitcoin into their balance sheets or investment portfolios.In addition, traditional financial institutions have begun launching cryptocurrency-related products. For example, ProShares’ Bitcoin futures ETF received approval from the U.S. Securities and Exchange Commission (SEC) in October 2021, marking a key step toward the integration of Bitcoin into mainstream financial markets and significantly boosting market confidence and legitimacy.

Macroeconomic Factors and the Inflation Hedge Narrative
In 2021, the global economy faced numerous uncertainties, particularly against the backdrop of the COVID-19 pandemic. Quantitative easing policies and fiscal stimulus measures implemented by central banks around the world sparked market concerns about inflation.In this macroeconomic environment, many investors began to view Bitcoin as a form of “digital gold,” believing it serves as a hedge against inflation and a store of value. This narrative drove demand for Bitcoin to some extent, propelling it to an all-time high of approximately $68,742 in November 2021.The Federal Reserve’s monetary policy, particularly the direction of interest rates, has also indirectly influenced the cryptocurrency market. Accommodative monetary policy typically encourages investment in risky assets, while tightening policies may dampen market interest in speculative assets.

Regulatory Developments and Government Policies
Government regulatory stances and policy changes had a significant impact on the price of Bitcoin in 2021. Positive regulatory developments, such as El Salvador becoming the world’s first country to adopt Bitcoin as legal tender on September 7, 2021—a move aimed at enhancing financial inclusion—sent positive signals to the market.On October 15 of the same year, the U.S. SEC approved the first Bitcoin futures ETF, further strengthening the legitimacy of Bitcoin and providing institutional investors with easier access to the market.However, negative regulatory news also had a significant impact. For example, China’s comprehensive crackdown on cryptocurrency mining operations in 2021 caused the hash rate of the Bitcoin network to plummet at one point, which is considered one of the key factors behind the Bitcoin price correction in late 2021. Regulatory uncertainty has always been a major source of Bitcoin price volatility.

Tesla The Impact of Bitcoin and Its Founder, Elon Musk
Tesla Elon Musk, the company’s CEO, had a unique and at times dramatic impact on the Bitcoin market in 2021. As mentioned earlier, Tesla’s purchase of Bitcoin in February 2021 and its announcement that it would accept Bitcoin payments significantly boosted market sentiment and prices.However, on May 12, 2021, Musk suddenly announced that Tesla was suspending acceptance of Bitcoin payments due to environmental concerns. This statement caused the price of Bitcoin to drop by 12% that day and fall by approximately 40% over the following week.This incident highlighted how statements from a small number of highly influential public figures or companies could cause significant short-term volatility in market sentiment and asset prices within the relatively immature cryptocurrency market at the time.

Market Sentiment, Supply and Demand, and Liquidity
Bitcoin has a fixed total supply of 21 million tokens, and this scarcity forms the foundation of its value narrative.During the bull market from late 2020 through 2021, sustained buying by institutional investors and a surge in “fear of missing out” (FOMO) sentiment among retail investors led to a sharp rise in market demand, while the supply of Bitcoin could not increase rapidly,and this supply-demand imbalance was a key factor driving the price from approximately $10,000 to nearly $69,000.Market sentiment is highly sensitive to news and social media; positive news and institutional adoption drive up demand, while negative news can trigger sharp sell-offs. Furthermore, compared to traditional financial markets, liquidity in the Bitcoin market was relatively low at the time, meaning large buy and sell orders could have a greater impact on prices, thereby exacerbating market volatility.
