Bitcoin is now confronting its largest supply barrier, with the price also nearing the key 50-week moving average.
The main resistance zone sits between $80,000 and $82,000, where Bitcoin has its biggest concentration of supply across a similar price range.
Glassnode’s Realized Price Distribution (URPD) indicates that almost 8% of Bitcoin’s supply was purchased within this range. The metric maps existing holdings to the prices at which they were last acquired, showing where different portions of the supply have their average cost basis.
The $80,000 level alone accounts for roughly 5% of Bitcoin’s supply, making it the largest single-price concentration. Around 3.7% of supply is clustered near $78,000, while $82,000 ranks as the fourth-largest supply level.
Such clusters can create selling pressure when Bitcoin revisits them. Holders who bought near these prices may choose to take profits or exit positions once BTC reaches their original purchase price, creating additional resistance.
The potential supply pressure is also amplified by the $80,000-$82,000 average cost basis of deposits into U.S. spot Bitcoin ETFs, according to Glassnode.
Bitcoin previously encountered a comparable supply concentration between $60,000 and $63,000, where more than 6% of total supply was held. That region later became a significant support zone after BTC spent much of 2026 trading within the range. Even when Bitcoin briefly slipped below $60,000 during the summer, it quickly recovered.
The 50-week moving average is another major level to watch. It currently stands near $81,081, representing Bitcoin’s average closing price over the previous 50 weeks.
Bitcoin has remained below the indicator since November 2025. However, previous sustained moves above the 50-week moving average, including breakouts in May 2020 and March 2023, were followed by prolonged bullish trends.
