  [Comprehensive News Analysis]
  Summary: Today's crypto landscape is dominated by the ongoing narrative surrounding Craig Wright's copyright claims, which have fueled a significant surge in Bitcoin SV. Meanwhile, concerning news regarding Tether's partial backing by Bitcoin and potential solvency issues for Bitfinex is creating bearish pressure and raising questions about market stability. On the regulatory front, Russia is delaying its crypto legislation, and the US SEC has again delayed its decision on a Bitcoin ETF, though the market appears largely unfazed by the latter. Despite mixed signals, prominent analysts like Thomas Lee are bullish on the overall market, suggesting the crypto winter may be over.
