The digital asset market witnessed unprecedented growth in 2021, marking a historic milestone in its evolution. By November, the total market capitalization surged to nearly $3 trillion**, closing the year at **$2.25 trillion—an impressive annual increase of almost 200%. Bitcoin and Ethereum repeatedly shattered previous all-time highs, peaking at approximately $70,000** and **$5,000, respectively.
This explosive growth was mirrored in trading activity across both centralized and decentralized platforms. The total trading volume for the year reached an astonishing $112 trillion**, with perpetual contracts accounting for about half—**$57 trillion—while spot trading contributed $49 trillion (43%). The remaining volume came from delivery contracts and options. Compared to 2020, overall trading volume grew by 3.37x, with perpetual contracts seeing the most dramatic rise—nearly 6x growth—followed by spot trading (2.3x), delivery contracts (2.36x), and options, which also expanded nearly 6x.
Spot Market Landscape: Dominance, Shifts, and Emerging Players
In the spot trading arena, Binance maintained its position as the market leader. With nearly $11 trillion in annual spot volume, it captured 41% of the combined volume from the top 16 exchanges and approximately 22% of the entire market—including both centralized and decentralized exchanges (CDEs and DEXs).

However, significant shifts occurred among other major players. Huobi, once a top contender, saw its market share plummet from around 16% at the beginning of the year to just 7% by year-end, following its announcement to cease services for users in mainland China. Regulatory pressures significantly impacted its global standing.
On the rise were platforms like Upbit, South Korea’s largest exchange, which benefited from renewed "kimchi premium" dynamics during bull market surges. Meanwhile, FTX nearly doubled its market share, and KuCoin increased its footprint by 3.32 percentage points, ending the year at 4.34%.
One of the standout performers was Crypto.com, emerging as a dark horse with a year-end market share of 5.16%, fueled by aggressive marketing, card programs, and strategic partnerships.
U.S.-Based Exchanges: Compliance Meets Growth
In the United States, regulatory compliance played a pivotal role in shaping market dynamics. Coinbase solidified its dominance after becoming the first major crypto exchange to go public via a direct listing on Nasdaq. It commanded roughly 50% of the U.S. market share, followed by Kraken (20%), Crypto.com (15%), Binance US (9.5%), and FTX US (1.95%).
Growth momentum in the second half of the year favored newer entrants: Binance US, FTX US, and Crypto.com all reported substantial increases in user adoption and trading volume, reflecting rising demand for compliant access to digital assets.
Platform Tokens: Stellar Performance Amid Market Surge
Platform tokens delivered extraordinary returns in 2021, riding the wave of increased exchange activity and ecosystem expansion.
- BNB (Binance) peaked in Q2 with a staggering 6,332% gain and posted a full-year return of 12.5x
- KCS (KuCoin) led the pack with an astonishing 30x return
- CAKE (PancakeSwap) followed closely with 16.7x
- GT (Gate.io) achieved 11.6x
- CRO (Crypto.com) delivered 8.3x
These figures underscore the strong correlation between exchange performance and native token valuation—especially in ecosystems that reinvest revenue into buybacks, staking rewards, or utility enhancements.
Perpetual Contracts: Binance Leads, But Competition Heats Up
Perpetual futures remained a cornerstone of crypto derivatives trading. Binance dominated this segment with 40.8% market share, followed by Huobi (11%) and Bybit (7.6%).
More importantly, market share trends revealed deeper structural changes:
- Binance’s share rose from 41.8% in January to 56.87% by December—a gain of over 15 percentage points
- OKEx, FTX, and KuCoin each gained between 2% to 4%
- Conversely, Huobi’s share collapsed from 22.88% in January to just 3.48% in December, largely due to regulatory setbacks
- Notably, decentralized exchange dYdX emerged as a key player, capturing 2.22% of quarterly volume in Q4, driven by its liquidity mining incentives
Open Interest Growth: Gate.io Shines Among Challengers
Open interest—the total value of outstanding derivative contracts—also reflected shifting competitive dynamics.
Top platforms by open interest included:
- Binance
- FTX
- Bybit
Year-on-year growth leaders stood out:
- Gate.io: up an incredible 538x
- KuCoin: +611%
- FTX: +580%
These numbers highlight how aggressive product development, leverage offerings, and user incentives fueled rapid expansion beyond the top-tier exchanges.
Options Market: Deribit's Growing Monopoly
The crypto options market matured significantly in 2021, with total annual trading volume reaching $460.6 billion—a sixfold increase from 2020.
Deribit reinforced its dominance:
- Held over 68% market share in Q1
- Expanded to 87% by Q4
- Became the first platform to surpass $100 billion in quarterly options volume
Meanwhile:
- OKEx saw its share drop from 25% to 9%
- Bit.com declined from 4% to 2%
This increasing centralization raises concerns about market resilience and counterparty risk—an area likely to attract greater scrutiny in 2025.
