Cryptocurrency News Today: Bitcoin FOMO sentiment reaches highest level since 2024!

Bitcoin's sprint to US$87,000 triggers a dramatic change in market sentiment

Bitcoin's rebound to US$87,000 triggered a dramatic change in sentiment in the cryptocurrency market. After weeks of turmoil, traders are increasingly discussing higher prices, while bearish rhetoric is overwhelmed by bullish expectations.

According to a chart shared by on-chain data analysis platform Sanitation, bullish comments in the crypto market soared to their highest level since December 2024 on September 21.

This enthusiasm follows Bitcoin's strong recovery, which has been accompanied by a massive rise in short clearing and trading activity. However, the same data also raises an important question: Are markets becoming optimistic too quickly?

Bitcoin's FOMO (phobia of missing) reaches its highest level since December 2024

Sanitation's chart tracks social media comments containing bullish and bearish language and compares it with Bitcoin's price movements.

The red bar chart represents bullish discussions, and the blue bar chart tracks bearish comments. The green line shows the price of Bitcoin during the same period.

There are three significant periods in the chart:

In late June, when Bitcoin fell below $60,000, bearish comments surged. The chart records a particularly large wave of panic between June 21 and June 30, showing how negative sentiment quickly builds as prices fall.

The opposite situation occurred around August 19 and 20. A wave of bullish comments accompanied Bitcoin's recovery, but subsequent gains stalled.

The latest readings are even more eye-catching.

The bullish reading reached 954, while the bearish comment was 269, when Bitcoin was trading close to $86,700. This means that for every bearish mention in the language categories tracked by the chart, there are approximately 3.5 bullish mentions.

Sanitation identified this as the largest peak of bullish comments since December 2024.

This comparison is significant because it shows that optimism has reached abnormally high levels. However, social media activity does not represent a scientific survey of all cryptocurrency investors, and emotional extremes do not reliably identify the exact moment of market reversal.

Short squeeze adds fuel to Bitcoin's rally

The surge in sentiment coincides with a wave of forced buying in the cryptocurrency market.

According to market data provided with the analysis, approximately US$648 million of bearish crypto positions were cleared within 24 hours, while total cryptocurrency trading volume increased by 39%.

When traders establish short positions, they usually benefit from falling prices. If the market goes up, their positions could be liquidated, forcing these trades to be closed.

This process can accelerate existing gains, as the purchase from short liquidations increases demand in other markets.

The combination of rising prices, large short liquidations and increased trading activity helps explain why the recovery has been so rapid this time.

但是，仅凭清算量无法确定比特币的涨幅中有多少来自真正的现货买入，又有多少来自衍生品活动。

它们还为在最大涨幅发生后入场的交易者带来了一个潜在问题：推动价格走高的强制买入可能不会以相同的速度持续下去。

未平仓合约的增加发出另一警告

尽管据报道有6.48亿美元的空头被清算，但根据帖子附带的数字，总加密货币未平仓合约（Open Interest）增加了7.6%，至约1560亿美元。

未平仓合约衡量的是未结清的衍生品合约数量。当它上升时，表明总体上打开的头寸多于关闭的头寸。

因此，这表明在经历了一次大规模的清算事件后，杠杆交易中的参与度仍在继续。

然而，未平仓合约的增加并不能证明交易者正在大规模建立新的多头头寸。每一份衍生品合约都涉及多头和空头两面，需要更多信息来确定持仓情况的变化。

令人担忧的是，高杠杆可能会放大价格在任何方向上的波动。

如果比特币继续攀升，杠杆头寸可能会导致进一步的波动。如果价格逆转，那些在高杠杆下后期入场的交易者可能面临自己的头寸被清算的风险。

Sanitation's sentiment data adds another dimension to this risk. Markets have shifted from apparent fear in June to unusually strong optimism in September.

This extreme situation sometimes occurs near local turning points, but it may also persist in a sustained rebound.

Another cryptocurrency development: Cardano enters AI payments space

In addition to Bitcoin's rebound, Cardano also announced a development involving AI-driven payments.

In an announcement released on September 21, the Cardano Foundation stated that Cardano is now part of the official x402 software development kit.

The integration is designed to allow applications and AI agents to pay for API calls via Web requests using ADA or Cardano native tokens without the need for a traditional checkout process.

This creates potential use cases for automated payments, including AI agents purchasing data or computing services.

However, the integration has not established a large amount of payment traffic or new demand for ADA has emerged. Adoption rates will depend on how developers implement the feature and how users transact through it.

This announcement provides an independent example of blockchain infrastructure development underway while speculative interest in the broader cryptocurrency market is increasing.

What does extreme Bitcoin optimism mean for prices?

Bitcoin's recovery has brought substantial improvements in market structure, but the latest sentiment readings have introduced additional risks.

Sanitation's chart shows that just as Bitcoin approaches $87,000, bullish comments have reached extraordinary levels. The large number of short liquidations and rising open interest contracts suggest that derivatives trading played an important role in this round.

For bulls, continued buying could allow Bitcoin to consolidate above former resistance and continue its recovery.

For bears, the concern is that traders become overconfident after a rapid rise, and the market risks a correction if buying pressure abates.

The bottom line is: Bitcoin's rebound is real, but extreme optimism does not guarantee further gains. The next test will be whether the market can maintain its recovery momentum after the short squeeze subsides and traders begin to reassess their positions.
