Bitcoin and Ethereum price action today

Bitcoin (BTC) traded at around 63,944 US dollars on 17 July 2026, down approximately 1.01% over the previous 24 hours, with roughly 26.83 billion US dollars in trading volume, according to data reported by CoinGabbar citing CoinMarketCap (17 July 2026). Ethereum (ETH) traded at around 1,866.92 US dollars, down approximately 2.39% over the same period.

The total cryptocurrency market capitalisation stood at around 2.27 trillion US dollars, down about 1.6% in 24 hours, with Bitcoin's share of the total market, known as dominance, at approximately 56.3% and Ethereum's dominance at approximately 9.88%, per the same source.

What the Fear and Greed Index is showing

The crypto Fear and Greed Index is a sentiment gauge, not a price indicator. It combines data such as volatility, trading volume, social media activity, and market momentum into a single score between 0 and 100. A reading closer to 0 indicates Extreme Fear, while a reading closer to 100 indicates Extreme Greed, according to crypto data provider Milk Road, which publishes one version of the index.

As of 17 July 2026, this reading stood at 27, described as Fear, a marginal improvement from 25 the day before, according to CoinGabbar (17 July 2026). It is worth noting that different providers run their own versions of this index using different inputs and methodologies, so exact readings can vary between sources. CoinStats AI, for example, reported a reading of 26 on 16 July 2026, up from an average of around 20 over the prior week (CoinStats AI, 16 July 2026).

Why the exact number varies by provider

Because no single, official version of the Fear and Greed Index exists, readers comparing figures across different crypto news sites may see slightly different scores on the same day. This reflects differences in each provider's inputs and weighting rather than a disagreement about the underlying market data.

Why sentiment remains weak

Several factors have kept sentiment subdued through July 2026. Crypto exchange traded fund (ETF) flows have been inconsistent, with some sessions showing inflows and others showing outflows, reflecting broader caution among institutional investors, according to FXStreet (14 July 2026). Macroeconomic uncertainty, including interest rate expectations and geopolitical developments, has also weighed on risk appetite across markets more broadly.

ETF flows and the macro backdrop

FXStreet reported that Bitcoin spot ETFs experienced further outflows in mid July 2026 alongside continued geopolitical tensions, before some sessions later in the month showed a partial return of inflows (FXStreet, 14 July 2026). This kind of flow volatility is one factor analysts point to when explaining why sentiment gauges have stayed in Fear territory for an extended period, rather than any single cause.

What extreme fear has meant historically

According to Milk Road, extremes on the Fear and Greed Index have historically been a somewhat better indicator of market bottoms than of market tops, though the provider itself cautions that prices can move for many reasons and that no single indicator should be relied upon in isolation. This is a historical observation, not a guarantee of future performance, and past patterns may not repeat.

• Extreme Fear readings have historically coincided with periods of panic selling and forced liquidations of leveraged positions, according to Milk Road.
• Extreme Greed readings have historically coincided with optimism driven buying, sometimes linked to fear of missing out, per the same source.
• Sentiment indices are one input among many that some market participants monitor, alongside price, volume, and news flow.

Cryptoassets remain highly volatile and largely unregulated in the UK, and losses can exceed initial expectations. This section describes historical patterns only and should not be read as a signal to act.

• Sentiment gauges such as the Fear and Greed Index remain in Fear territory, though readings vary slightly between providers.
