"Bitcoin ETF Anticipation Sparks Trading Frenzy as SEC Decision Looms"
Bitcoin traders are showing less bullish behavior as the SEC's deadline for approving spot exchange-traded funds (ETFs) approaches on January 10. The premium for calls over puts has decreased from 8% to around 2%, indicating a more cautious sentiment. The market is also bracing for potential volatility, with one-week options implied volatility having nearly doubled since December 29. Analysts suggest that the impact of ETFs on bitcoin's price may be gradual rather than immediate, and while short-term volatility is expected to increase, the long-term effects on price turbulence are still uncertain.
