Bitcoin has fallen below US$75,000 as cryptocurrency markets extend their recent sell-off, with Ethereum, Solana and XRP also under pressure amid heavy ETF outflows and renewed concerns over US regulation.

Bitcoin was trading around US$74,700, down about 1.5% over 24 hours, after briefly touching US$73,700, its lowest level since August.

Ethereum was around US$2,120, down roughly 5%, while Solana traded near US$86.60 and XRP around US$1.12.

The broader market remained firmly risk-off, with only a small number of major tokens posting gains over the latest session.

Institutional flows remain one of the biggest headwinds.

US spot Bitcoin ETFs recorded US$430.2 million of net outflows on November 5, followed by another US$411.9 million on November 6, taking seven-day withdrawals to about US$1.9 billion.

Ethereum ETFs also suffered US$93.3 million of outflows on November 6, while Solana funds lost about US$25 million.

The continued redemptions suggest institutional appetite has weakened materially after months in which ETF demand had provided one of crypto’s strongest sources of support.

Bitcoin and Ether both touched their lowest levels in more than two months in late Sunday trading as investors reassessed the regulatory outlook.

That concern has compounded the fallout from the recent Binance hack, which has already shaken confidence in centralised exchanges.

Bitcoin is now testing the US$73,000-US$75,000 region, with liquidity clustered around the lower end of that range.

A sustained break below US$73,000 could trigger another round of deleveraging, while a recovery above US$76,000 would be the first sign that selling pressure is beginning to ease.

For now, the combination of ETF outflows, regulatory uncertainty and weak broader risk appetite is keeping crypto markets on the defensive.
