Bitcoin’s rally is approaching a $90,000 test as a rare accumulation pattern reappears and sell-side liquidity thins.

On Oct. 2, Bitcoin registered an intraday high at $87,000 after buyers broke through a sell wall around $85,000 that had stalled several previous attempts to advance.

Glassnode said some of those orders were filled and the remainder withdrawn, leaving a smaller concentration of asks around $87,000 and less visible liquidity immediately above.

At the same time, bands on CryptoQuant’s Bitcoin Accumulation Trend chart have begun contracting, reviving a pattern seen before two sharp advances in 2025.

The setup adds another bullish signal to a market that has reclaimed several key cost-basis levels, though the limited number of previous occurrences makes the pattern far from conclusive.

Per CryptoQuant, the current contraction resembles two episodes in 2025 followed by sizable gains, giving traders a bullish analog as Bitcoin enters October .

The Accumulation Trend tracks buying and selling behavior across different groups of Bitcoin holders, offering a view into whether supply is being absorbed or distributed. Periods when the chart’s bands narrow sharply have previously coincided with shifts in market momentum.

One contraction occurred between April 17 and April 20, 2025, when Bitcoin traded near $84,000 . BTC subsequently climbed toward $109,000, and another appeared between March 5 and March 8 before a separate advance.
