The Top 20 Cryptocurrencies in April 2021
The market was dominated by established giants and a few surging newcomers. Here’s a closer look at the projects that made up the top twenty.
The Undisputed Leaders: Bitcoin and Ethereum
- Bitcoin (BTC): Firmly holding the number one spot, Bitcoin’s market cap exceeded a staggering $1 trillion. Its price hovered around $58,750, reflecting strong institutional and retail investor confidence. It served as the foundational store of value for the entire ecosystem.
- Ethereum (ETH): As the leading smart contract platform, Ethereum’s price was above $2,000, pushing its market cap to over $241 billion. It was the backbone of the rapidly expanding decentralized finance (DeFi) and non-fungible token (NFT) applications, fueling its growth.
Major Altcoins and Stablecoins
The next tier was a mix of exchange tokens, smart contract platforms, and essential stablecoins.
- BNB: Binance Coin experienced tremendous growth, capitalizing on the success of the Binance Smart Chain, which emerged as a popular alternative for DeFi users seeking lower transaction fees.
- Stablecoins: Tether (USDT) and USD Coin (USDC) were firmly embedded within the top twenty, highlighting their critical role as the primary on-ramps and off-ramps for crypto trading and a safe haven during market volatility.
- Smart Contract Competitors: Polkadot (DOT) and Cardano (ADA) were prominent players, both presenting themselves as next-generation networks aiming to overcome Ethereum's scalability limitations.
Notable Performers and Surging Assets
This period saw explosive growth for several specific assets, indicating strong market trends.
- DeFi Tokens: Uniswap (UNI) and Chainlink (LINK) represented the explosive growth of the DeFi sector, providing essential infrastructure like decentralized exchanges and oracle services.
- High-Growth Assets: Tokens like THETA, Filecoin (FIL), and particularly BitTorrent (BTT) and TRON (TRX) posted astonishing 24-hour and 7-day gains, in some cases exceeding 100%. This indicated a market ripe with speculation and momentum-driven trading.
Key Market Trends in Early 2021
The data from this snapshot reveals several overarching trends that defined the 2021 bull market.
The Rise of DeFi and Staking
Decentralized Finance was no longer a niche concept but a major market force. The high valuations of DeFi-related tokens underscored the massive capital flowing into protocols for lending, borrowing, and yield farming. Similarly, the success of projects like Polkadot highlighted a growing interest in staking as a method to earn rewards on held assets.
The Speculative Momentum Wave
The incredible percentage gains seen by assets like BTT and TRX were characteristic of a highly speculative market. Retail investors, driven by social media and the fear of missing out (FOMO), were actively seeking out low-cost tokens with the potential for high returns, regardless of their underlying utility.
Institutional Adoption Grows
Bitcoin’s trillion-dollar market cap was a clear signal of deepening institutional adoption. Major corporations and financial institutions were increasingly adding Bitcoin to their balance sheets, lending credibility to the entire asset class and driving its price to new highs.

Frequently Asked Questions
What was the total cryptocurrency market cap in April 2021?
While this snapshot shows the top assets, the total market capitalization for all cryptocurrencies was significantly larger, consistently hovering in the range of $1.5 to $2 trillion during this period, reflecting a massive influx of capital into the space.
Why were stablecoins like USDT and USDC so highly ranked?
Stablecoins are pivotal to crypto trading. They act as a dollar proxy, allowing traders to move in and out of volatile assets without converting back to fiat currency. Their high trading volumes and circulating supply naturally lead to large market caps.
What caused the huge price gains for tokens like BitTorrent (BTT)?
These massive short-term gains were typically driven by a combination of factors: hype on social media platforms, strategic announcements from the development teams, and a general wave of speculative trading where retail investors chased momentum.
How does the market composition then compare to today?
The core top five assets have remained relatively consistent, but the rankings beneath them have shifted dramatically. Many projects from the top 100 in 2021 have faded, while new ones focusing on scalability and other innovations have emerged to take their place.
Was Ethereum's high fee problem a factor in April 2021?
Yes. Ethereum's scalability issues, leading to high gas fees, were already a major topic of discussion. This directly contributed to the rise of competitors like Binance Smart Chain and fueled the growth of "Ethereum killer" projects.
What happened to the market after this snapshot?
The bull run continued for several more months, with Bitcoin and Ethereum reaching all-time highs later in the year. However, the market eventually corrected, entering a bear market phase in 2022, demonstrating the highly cyclical nature of the industry.
