Analytics platform Swissblock says one metric indicates that a local bottom is in for Bitcoin (BTC) and altcoins.

In a new post on X, Swissblock says the crypto market is in a reset phase based on its Aggregated Impulse metric, which measures exponential price structure across the top 350 assets.

According to the analytics firm, the metric has been a reliable bottom signal for BTC and altcoins since 2024.

“The last seven times this signal triggered since 2024, it marked a major bottom.

What happened next?

BTC rallied +20–30%

Altcoins surged +50–150%…

What’s it telling us now?

22% of altcoins show negative impulse. Historically, bottoms form in the 15–25% zone. Once the reset completes, ETH & alts tend to lead the next rotation.”

Looking closer at Bitcoin, Swissblock sees consistent demand for BTC from multiple investor cohorts, while noting that sellers are losing ammunition.

“Bitcoin’s range is nearing resolution.

• 10 weeks trapped in $109,000–$124,000.
• LTH (long-term holder) distribution slowing? seller exhaustion close.
• ETFs (exchange-traded funds) + treasuries persistent buyers.
• Seasonality flips bullish into Oct/Nov.
• Fed easing cycle adds tailwinds.

Swissblock Vectors show the inflection:

Bitcoin Vector: Impulse score compressing at the upper band? coiled energy.
Altcoin Vector: Breadth improving, ETH + majors rotating higher.

Key trigger: A reset through negative aggregated impulse would flush weak hands and reload the signal? clearing the path for continuation.

This deadlock is not permanent. Once supply clears, Q4 setup favors a decisive breakout in both Bitcoin and altcoins.”

At time of writing, Bitcoin is valued at $109,603.
