"Greed and Fear Index" Revealed: How to Use Market Sentiment to Capture BTC Buying and Selling Opportunities

This indicator quantifies market sentiment with numbers, helping investors make more rational decisions during extreme emotions.
The Quantitative Code of Market Sentiment
The Greed and Fear Index is a scoring system from 0 to 100 that translates the collective psychology of the market into a clear, visible number. Imagine the market as a person—sometimes it is extremely pessimistic, sometimes it is wildly optimistic—this index acts as a "mood thermometer" for the market.
The index has five emotional zones:
- 0-24 (Extreme Fear): The market is in panic, with people rushing to sell, and prices may be severely undervalued. For the bold,

In the past, you could only buy and sell on crypto exchanges, but since the U.S. Securities and Exchange Commission approved the first Bitcoin spot ETF in early 2024, traditional financial systems have opened a new door for ordinary investors. Now, you can choose to buy Bitcoin ETFs just like stocks, without managing private keys or worrying about exchange security issues—everything has become much simpler.
This policy shift is not just a regulatory compromise but a milestone in the deep integration of crypto assets with traditional finance. For retail investors, it means that Bitcoin investment has finally evolved from a "highly technical activity" to a "daily asset allocation option." What exactly is a Bitcoin ETF, is it suitable for you, and how can you start investing? This comprehensive guide will answer all these questions.

The Hidden Costs of Wall Street: Why Gold Has Attracted More Capital Than Bitcoin

Gold has long been considered a safe haven and a store of value, especially during times of economic uncertainty. However, recent trends show that the capital flowing into gold has been significantly higher than that into Bitcoin, raising questions about the underlying reasons behind this shift.

![Gold bars stacked in a vault](https://example.com/images/gold-vault.jpg)
*Alt text: Gold bars stored in a secure vault*

This phenomenon can be attributed to several factors, including regulatory environments, market maturity, and investor perceptions. While Bitcoin offers decentralization and technological innovation, gold remains a tangible asset with a long-standing history of stability.

### Factors Influencing Investment Flows
- **Regulatory Clarity**: Governments and financial institutions have established clearer regulations for gold trading, making it a safer choice for many investors.
- **Market Maturity**: The gold market is well-established, with extensive infrastructure and liquidity, whereas Bitcoin's market is still evolving.
- **Perception of Stability**: Gold is perceived as less volatile and more reliable, especially during economic downturns.

In conclusion, the "silent cost" on Wall Street refers to the opportunity cost and risk aversion that drive investors toward gold over Bitcoin, despite the latter's innovative potential. Understanding these dynamics is crucial for anyone looking to navigate the evolving landscape of alternative assets.
Gold and Bitcoin have recently shown divergent market performance, reflecting the economic issue of sunk costs behind capital shifting. Gold, as a long-term safe-haven asset, performs steadily during market panic, while Bitcoin is viewed as a short-term speculative tool. The market's choices embody a game of consensus systems: the historical trust in gold versus the future faith in Bitcoin. In times of increased uncertainty, capital tends to favor gold over Bitcoin, but this trend may change in the future.

Bitcoin Flash Crash During U.S. Stock Market Closure: From 75,800 to a Heavy Hit to Institutional Cost Basis
The weekend crypto market experienced a rapid correction, with Bitcoin dropping from $82,000 to $75,800, reflecting capital flow pressures and market liquidity stress. During the US stock market holiday, the crypto market became a venue for large-scale adjustments. This decline broke through MicroStrategy's cost basis of $76,000, impacting market psychology. $70,000 is a key support level; falling below it could trigger miners to shut down, leading to new supply and demand shifts. Market panic selling may signal entry opportunities, and the liquidity turning point is expected to bring a rebound. Understanding cross-asset correlation effects is crucial for market participants.

A meme reveals the truth: Dogecoin's founder exposes the underlying reasons behind this wave of crypto market correction
The recent cryptocurrency market has experienced a significant decline, with Bitcoin dropping from $93,300 to $86,400, reflecting that funds are prioritized for sale of high-risk assets during times of panic. Dogecoin co-founder Billy Markus used a meme to succinctly express market sentiment, showing investors shifting towards traditional safe-haven assets like gold and silver. Market risk appetite has plummeted sharply, making it difficult for cryptocurrencies to rebound in the short term. Future recovery will depend on geopolitical and trade developments to restore risk sentiment.
