## Bitcoin Options Expire Today: $3.5 Billion on the Line A significant Bitcoin options expiry event is happening today, potentially impacting the market. According to Deribit, a leading cryptocurrency options exchange, approximately $3.5 billion worth of BTC options are set to expire today, November 21st, at 17:00 Korean time. The put/call ratio for this expiry is 0.59, indicating slightly more call options than put options are in play. The "max pain" price, the price at which the most options contracts will expire worthless, is estimated at $99,000. This suggests that option writers are positioned for Bitcoin to remain below that level at expiry. ## Ethereum Options Expiry Also Looming In addition to Bitcoin, Ethereum options worth $520 million are also expiring simultaneously. The put/call ratio for ETH options is 0.73, and the max pain price is $3200. This expiry could introduce volatility to the ETH market as well. Traders are advised to monitor price movements closely. ```
