Bitcoin Becomes More Volatile Than Ether as Halving Approaches

Summary

Bitcoin's volatility has surpassed that of ether, with its 30-day historical volatility reaching nearly 60%, exceeding ether's by 10 percentage points. The SEC's approval of spot bitcoin ETFs has driven attention to bitcoin, while the dwindling probability of an ETH ETF approval has demotivated ether traders. Bitcoin's upcoming reward halving, reducing per-block BTC emission, may contribute to higher volatility. The market anticipates a "sell-the-news" pullback after the halving, with the options market pricing in the event's impact on volatility.
