Bitcoin options expiry data: 18,000 contracts expiring
Data from CoinWorld: GreeksLive reports that on October 16, 18,000 Bitcoin options contracts expired, with a put-to-call ratio of 1, a maximum strike price of $83,000, and a notional value of $1.47 billion. On today's expiry date, 4.5% of Bitcoin options positions expired. This week, the U.S. stock market sharply pulled back due to poor macroeconomic data, and the cryptocurrency market also fell in tandem, with weak market performance. Implied volatility (IV) is currently at a low level, with 35% as the bottom, and the market's expectation for future price fluctuations is extremely low. Despite the strong market performance in summer, high IV has not yet appeared in the main options market, and buyers remain cautious and unwilling to pay a premium. GEX is gradually converging toward $90,000, and Gamma is beginning to accumulate in $80,000 put options. Cryptocurrencies experienced a strong rebound in summer, marking a two-month small bull market. Considering the low monthly out-of-the-money IV, establishing put protection is still worthwhile, and continuing to roll these positions also has value.

Hardware Wallets: A Detailed Explanation of Cryptocurrency Cold Storage
According to news from Bijie, Decrypt reports that a hardware wallet is a dedicated physical device, usually similar in size to a USB flash drive or a credit card, used to generate and store the private keys of cryptocurrencies. It is a form of "cold storage" because the private keys remain offline. The main advantage of a hardware wallet lies in isolation: even if malware exists on a computer, an attacker cannot extract the private keys from a well-designed hardware wallet or approve transactions without the user's confirmation. In recent years, hardware wallets have continuously improved, evolving from small screens and clunky interfaces into modern devices that integrate Bluetooth, NFC, and even touchscreens and cameras. Companies such as Ledger and Trezor occupy an important position in the hardware wallet market, and Ledger's recently launched device ATOM aims to expand its functionality, supporting messages, applications, and agentic finance.
