Calculated through multiple factors, it measures the overall sentiment in the cryptocurrency market. Simply put, it reflects the level of "fear" (panic selling) and "greed" (FOMO chasing) among investors: the higher the index → the greedier the investors → the market is overheated, and the risk increases; the lower the index → the more fearful the investors → the market is oversold, and opportunities arise.
Historically, every extreme low point of the index has almost always coincided with market bottoms:
Bear market of 2018-2019: The index often stayed between 10-20, with BTC dropping from $20,000 to $3,000, but then rebounding to start a bull market. The 2022 FTX crisis: The index fell to 22, with BTC hitting a bottom of $15,000, then rebounding over 6 times.
Volatility in 2025-2026: The index dropped to between 9-16 (as it is now), corresponding to BTC's pullback from its $100,000 peak, with many analysts on Twitter viewing it as a "legendary bottom."

From the perspective of new investors, this index provides a simple contrarian strategy: when the index is extremely low (extreme fear), the market has priced in the worst expectations, presenting a potential buying opportunity;
When the index is extremely high (extreme greed), the risk of a bubble is significant, and one should consider reducing positions. Why is it considered one of the "most accurate timing indicators"?
Because it integrates social factors, trading volume, and other crypto-specific elements, making it more aligned with the sentiment in the crypto space than traditional VIX, and historical data shows that buying at low points often leads to high returns.
The effective strategies to respond are actually quite simple: contrarian thinking, position control, and dollar-cost averaging. Contrarian thinking: When the index is high (greed), don’t FOMO chase highs; when the index is low (fear), don’t panic sell. "When the crowd is fearful, smart money is building positions." Historically, investors who bought when the index was between 10-20 at the bottoms of 2018/2022 later reaped substantial rewards. Position control: During extreme fear, buy in small batches with light positions, keeping cash to respond to further dips; during extreme greed, gradually reduce positions to lock in profits and avoid full position risks.
Long-term dollar-cost averaging: Regularly buy BTC, ETH, etc., even when the index is low, to accumulate at a low cost. Combine index signals to increase positions during fear and pause during greed, achieving "buy when no one is paying attention." The core idea: Use index data to combat emotional interference, making market fluctuations your ally rather than a burden.

Additionally, from real discussions on Twitter, many users view the index as a "mood ring" or "golden buying signal."
"Index 75 (high greed), while pushing prices up, requires caution for a pullback, keep strategies flexible." "Index 0-100 measures fear or FOMO; low points like extreme fear are spicy opportunities.
"Index 72 (greed), the market breaks $3 trillion in market cap, buyers are eager but need signal confirmation." These viewpoints confirm: when the index is low (like the current 14-16), it is a moment for "legendary births."
"The historical bottom patterns are the same; smart money builds positions in fear."
"Index 17 (extreme fear), do you see it as a buying window or keep cash?"
"Index 14 (extreme fear), index 32/100, is the time to buy the dip."
Daily updates like "Index 56 (greed) in August 2025, bull market is in control, but the fire is not out."
"Index 16 (extreme fear), whale accumulation indicates a reversal."
"Index 15, the market overreacts to macro, funds will shift to AI revenue companies."
"When the index is in single digits, don’t be misled by influencers; it’s unreliable but worth reading historical data."

The bottom area corresponding to the index low point (Data source: AiCoin) In these events, newcomers can follow several core principles: buy at the bottom in fear, build positions in batches: when the index is extremely low and BTC is probing lower levels, buy in batches.
