Sign of the week: The short-term fork’s cost base crossed below Bitcoin’s true median price: this crossover preceded drops of 21% in 2018 and 34% in 2022 in a single week. Bitcoin is trading today in a lower volatility environment, but could still reinforce a deeper correction.
Several weeks of mounting pressure broke. The index jumped back into high-impact territory for the first time since March, driven by a collapse in short-term holders’ earnings, one of the biggest ETF outflows in 2026, and a stablecoin run that signals buyers are turning away. The cross signal in the background adds uncomfortable historical context to what might come next.
About the Bitcoin Impact Index
The Bitcoin Impact Index measures which groups of Bitcoin holders are under financial stress, how severe that stress is, and whether it is severe enough to shake confidence in the direction of the market. It combines on-chain holder behavior, ETF and derivatives activity, and exchange-level liquidity flows into a single weekly score between 0 and 100. Unlike sentiment indicators, it deliberately excludes social media and volume data to focus on what participants do rather than what they say.
Scoring bands:
- Normal rotation (0–24) — routine profit taking, without structural change
- Elevated Repositioning (25–49) — specific groups changing position, uneven pressure across the market
- High impact (50–74) — widespread tension between multiple groups of holders and institutional flows simultaneously
- Critical Hit (75–100) — total capitulation: LTH losses, large ETF outflows, major liquidations and strong currency inflows at the same time
Week 21 (May 18 to 24): BII 55.2: high impact
Negative signs: everything moved in the wrong direction at once
Short-term holders went from barely making a profit to being deeply undervalued.r in a week. Their realized P/Ls experienced a deterioration in a single week that matches the scale of the declines seen in the most stressful weeks of January and February. As a result, recent buyers who had been breaking even now have significant losses and, when they fall under water, tend to sell.
Stablecoins recorded a daily average of $332 million in net exchange flows, meaning buyers who would normally step in to absorb selling pressure were not arriving. Furthermore, leveraged long positions continued to be the most affected by derivatives stress, with long settlements that represent 82% of the totalwith bullish leveraged positions being systematically eliminated.
Negative signals: a historical warning pattern has just appeared
The short-term fork’s cost base crossed below Bitcoin’s true median price, and this crossover historically occurred amid previous bear markets before each major drop:
- In 2014, a similar crossover preceded a weekly drop of 20%.
- In 2018, it preceded a weekly drop of 21%.
- And in 2022, it preceded a weekly drop of 34%.
If Bitcoin repeats this pattern completely, this suggests that the asset may be retested. $60,000 in the short term. However, Bitcoin has considerably lower volatility in this cycle, so It is unlikely that these magnitudes will be repeated. But the direction of the signal has been consistent: this crossover has historically meant that the market’s structural support has gone from holding to giving way.
Furthermore, the importance is not the precise percentage. It’s that the average recent buyer is now underwater relative to a long-term valuation anchor, which historically creates a self-reinforcing dynamic in which falling prices force more sales, which pushes prices down.
Mixed signals: long-term holders continue to buy, but slow down
Long-term holders added around 30,000 BTC last week. This continues the accumulation streak that has gone on for months, but is a notable step down from the 80,000 BTC added the previous week and the record additions seen through April. LTH SOPR dropped slightly to 0.871, indicating that Long-term holders continue to accumulate while increasingly underwater.
Funding rates turned slightly positive this week, meaning the extremely short positioning that dominated throughout the spring has completely dissolved. Leveraged traders are no longer betting aggressively against Bitcoin. That eliminates a possible bullish catalyst: a short squeeze — from the short-term outlook.
What could happen next?
Considering the deterioration of on-chain metrics and historical context, the path of least resistance appears to be down. The bulls could still try to recapture the true average price and cost basis for the short-term holder at $78,000, or even test the 200-day moving average at $80,000 in the coming days. But if their attempt fails, this could reinforce a deeper correction.
For bears, the immediate target is $74,500, where the 128-day moving average lies. A clear break below that level would remove key support and restore the kind of bearish momentum not seen since February. If that subsides, the next significant level is $70,000.
As such, the historic crossover signal, two consecutive weeks of record ETF outflows, and a stablecoin run point to continued bearish pressure in the near term. The accumulation of long-term holders and a low sell-side risk index are the main structural counterweights. Whether those counterweights are enough to recover $78,000 (or whether this week marks the beginning of a more sustained decline) could be decided fairly quickly.
