July 21, 2021 was a day of dramatic contrasts in the cryptocurrency market. Bitcoin had just touched $29,300 the day before — its lowest level since late January — before staging a sharp rebound above $32,000. The recovery was real, but the fear was even more so. The widely tracked Crypto Fear and Greed Index (CFGI) had plunged to a reading of just 10, placing the market squarely in “Extreme Fear” territory. For traders and analysts watching the charts, the question was whether this was the beginning of a sustained recovery or just another dead-cat bounce in a brutal summer correction.
TL;DR
- Bitcoin dropped to $29,300 on July 20 before rebounding over 8% to above $32,000 on July 21
- The Crypto Fear and Greed Index registered a score of 10 — “Extreme Fear” — its lowest reading since March 2020’s Black Thursday crash
- 24-hour trading volume for BTC reached $28.2 billion, reflecting intense market activity
- Ethereum traded at approximately $1,991, also well below its recent highs
- Analysts drew parallels to the 2013 mid-bull correction, which preceded a 2,400% rally
The Drop and the Bounce
Bitcoin’s decline to $29,300 on July 20 marked the culmination of nearly three months of relentless selling pressure. The crash from April’s all-time high near $64,000 had been driven by a confluence of negative catalysts: China’s intensifying crackdown on cryptocurrency mining, Tesla’s suspension of Bitcoin payments over environmental concerns, and growing regulatory uncertainty across multiple jurisdictions. By late July, the total crypto market capitalization had fallen to approximately $1.3 trillion — a fraction of its May peak above $2.5 trillion.
But July 21 brought a shift. Bitcoin surged more than 8% from Tuesday’s low, reclaiming the $32,000 level with notable conviction. Trading volume spiked, with $28.2 billion in BTC changing hands over 24 hours. The rebound coincided with the highly anticipated “The B Word” conference, where Elon Musk, Jack Dorsey, and Cathie Wood made a public case for Bitcoin’s long-term prospects. Musk’s revelation that SpaceX holds Bitcoin and that he personally owns Ethereum and Dogecoin injected fresh optimism into a market desperate for positive catalysts.
Extreme Fear: What the Index Tells Us
The Crypto Fear and Greed Index, hosted on alternative.me, aggregates “emotions and sentiments from different sources and crunches them into one simple number” ranging from 0 (Extreme Fear) to 100 (Extreme Greed). On July 21, 2021, it registered a 10 — a remarkably low reading that reflected deep pessimism across the market.
This was not the first time the CFGI had hit such depressed levels in 2021. The index had also scored 10 in mid-June and again at the end of May, as the market reeled from China’s mining ban announcements. But the broader context was even more telling: the last time the CFGI had been at 10 or lower was during the March 12, 2020 crash known as “Black Thursday,” when Bitcoin plunged below $4,000 in a matter of hours amid a global pandemic-driven panic.
For contrarian investors, extreme fear readings are traditionally viewed as potential entry points. The logic is straightforward: when sentiment is at its worst, selling pressure may be exhausted, and assets are often available at significant discounts relative to their recent highs. History has shown that some of Bitcoin’s most dramatic rallies have begun from moments of maximum despair.
Technical Indicators Paint a Mixed Picture
While the Fear and Greed Index captured the emotional state of the market, technical analysis told a more nuanced story. TradingView’s technical indicators for BTC/USD showed that moving averages were largely in the “sell” range, reflecting the sustained downtrend from April’s highs. However, oscillators — which measure momentum rather than trend — were more “neutral,” suggesting that the selling momentum was waning and a potential reversal could be forming.
Some analysts pointed to historical parallels with the 2013 bull market cycle. In that cycle, Bitcoin had surged above $200 before crashing back to around $50 in a mid-cycle correction. That drawdown, while devastating at the time, was followed by an explosive rally of approximately 2,400% that took Bitcoin to its first four-digit all-time high above $1,000. The question on many traders’ minds in July 2021 was whether the current correction from $64,000 was the same kind of mid-cycle shakeout or the start of a prolonged bear market.
Ethereum and the Broader Market
Ethereum was not immune to the market turbulence. ETH was trading at approximately $1,991 on July 21, a far cry from its May high above $4,300. The Ethereum network was also preparing for its highly anticipated London hard fork, which included the controversial EIP-1559 fee-burning mechanism. On the same day, a consensus issue was discovered on the Ropsten testnet related to EIP-1559-style transactions, though the Ethereum Foundation’s development team was working to resolve it before the mainnet upgrade scheduled for early August.
The broader altcoin market told a similar story of recovery from oversold conditions. Major altcoins like Binance Coin (BNB), Cardano (ADA), and Solana (SOL) had all suffered significant drawdowns from their highs but were showing signs of stabilization. Total market cap across all cryptocurrencies hovered around $1.3 trillion, with Bitcoin maintaining its dominance at roughly 47%.
China’s Mining Crackdown Continues to Reshape the Industry
One of the most significant structural changes affecting the Bitcoin network in mid-2021 was China’s aggressive crackdown on cryptocurrency mining. Multiple provinces had ordered mining operations to shut down, leading to a dramatic drop in Bitcoin’s hashrate as miners either ceased operations or began relocating to more crypto-friendly jurisdictions like the United States, Kazakhstan, and Canada.
The exodus of Chinese miners had created short-term uncertainty but was widely viewed as a long-term positive for Bitcoin’s decentralization and environmental profile. With coal-powered mining operations being shut down and new operations launching in regions with access to cheaper renewable energy, the network’s energy mix was shifting — a trend that Elon Musk specifically cited as a condition for Tesla potentially resuming Bitcoin payments.
Why This Matters
July 21, 2021 captured the essence of crypto market cycles in a single day: extreme fear, sharp rebounds, and the constant tension between short-term panic and long-term conviction. The CFGI reading of 10 signaled that sentiment had reached a point of maximum pessimism, which historically has often preceded significant recoveries. Bitcoin’s 8% bounce from $29,300 showed that buying interest remained strong even at depressed levels. Combined with the positive catalyst from The B Word conference and the ongoing structural migration of mining operations away from China, the pieces were falling into place for what would eventually become a powerful fourth-quarter rally back to new all-time highs. For investors who could look past the fear, the data was pointing toward opportunity.

CFGI at 10 is historically one of the best buy signals. went back and checked and every time it hit single digits in the past two cycles the 1 year return was absurd
28.2 billion in volume on the bounce day. thats not retail fomo, thats institutional accumulation imo. retail was panicking not buying
comparing this to the 2013 mid cycle correction and that 2400% rally is wild. wish the article went deeper on what made that comparison valid beyond just the price action
ETH at 1991 during this. imagine buying sub 2k ether and having to wait 6 months to be in profit. that took real conviction
