Cryptocurrencies fell again on Sunday evening, with BTC and ETH hitting two-month lows: Reuters mentioned two concerns: the possibility that a Democratic-controlled Congress might tighten regulations on digital assets following the US midterm elections; and the continued impact of the previous major security incident on Binance on market confidence. Three levels need to be distinguished here. Confirmed facts: Prices have shown a significant downward trend, with BTC ETFs experiencing a net outflow of $1.2817 billion over the last five full trading days. Reasonable inference: Regulatory uncertainty, exchange security issues, and capital outflows may collectively suppress risk appetite.
