Bitcoin's Bull Score Index rose to 80, an "Extra Bullish" reading, when the cryptocurrency moved above $80,000 in September, compared with a neutral 50 at the same price in May. CryptoQuant Head of Research Julio Moreno said the difference reflects stronger underlying conditions. The index ranges from 0 to 100 and combines network demand, stablecoin liquidity and trader profit margins; scores above 60 indicate bullish conditions and potentially sustainable upward momentum. Bitcoin gained 14% over the past week to reach a seven-month high of $87,000 as sentiment improved following the SEC's push to create a cryptocurrency regulatory framework. Strategy Inc.'s latest Bitcoin purchase after a nearly month-long pause also supported the rally, while U.S. spot Bitcoin exchange-traded funds recorded $998.95 million in Monday inflows, their largest single-day total in 11 months. CryptoQuant founder Ki Young Ju said Bitcoin reclaimed its 365-day moving average at $83,000 and traded above $84,000, a level widely viewed as separating bear- and bull-market conditions. Kevin Capital cautioned that a move toward $93,000-$100,000 could precede a correction. Polymarket raised its estimate of Bitcoin exceeding $100,000 before year-end to 42% from 16% the previous week. BTC was up 1.20% over 24 hours at $86,483.14, according to Benzinga Pro.
