Bitcoin posted its highest daily close since January at $86,607, supported by $2.38 billion in ETF inflows. The weekly inflow total was the largest since October 2025. The figures were published in Bitfinex Alpha’s Issue 224 market weekly, according to the report.

Ethereum (ETH) short positions on Bitfinex surged over the past two weeks, rising from around 771 ETH to more than 101,000 ETH, an increase of roughly 13,000%. The figures point to a heavy concentration of bearish positioning, with many traders betting on an ETH decline. Such an extreme build-up in shorts could become potential fuel for a short squeeze if $ETH moves higher.

U.S. spot Bitcoin ETFs recorded about $2.49 billion of net inflows over four consecutive sessions in late September, lifting the broader crypto market. XRP and SOL led the advance, with short covering amplifying the Sept. 21 breakout. By contrast, BNB rose less, while higher U.S. Treasury yields pulled BTC back from its early-week high. The market reflected a rotation into altcoins alongside ongoing macro pressure.

BTC fell 2.48% to USD 84,179 as long liquidations reached USD 130.36M; USD 85,056 is the daily-close recovery trigger.

BSV gained 23.74% in 24 hours as turnover reached USD 53.54 million. Daily momentum is extended, with USD 25.52 the next confirmation level.

BCH rose 28.78% in 24 hours after a planned regulated futures launch, while USD 1.37B turnover and stretched momentum raise reversal risk.

BTC rose 5.22% to USD 85,678 as USD 60.60B turnover and BTC short liquidations sharpened a breakout test near USD 87,396.

On 2026-09-23, spot Bitcoin ETFs led by BlackRock recorded a $999,000,000 net inflow in a single day. It was the largest one-day inflow of 2026. The move points to a return in institutional allocation demand for crypto assets.
