Metaplanet $1.46M BTC option sale
On Oct. 3, Metaplanet made a move by selling put options, bringing in an extra 23.97 BTC, valued at about $1.46 million at the time. They sold 223 Bitcoin put option contracts with a strike price of $62,000, set to expire on Dec. 27, 2024. Bitcoin put options are financial contracts that let buyers sell their Bitcoin at a set price (known as the strike price) by or before a certain date.
Buyers aren’t obligated to sell; it’s just an option they can use. Metaplanet’s CEO, Simon Gerovich, explained that this technique helps them grow their Bitcoin holdings without taking on extra risk. Moreover, he mentioned that the company plans to earn returns by using options strategies on part of its assets.
Gerovich teamed up with SBI Holdings’ crypto division in early September to boost its crypto trading, storage, and management features. SBI Holdings, a major player in Japan’s financial industry, is part of one of the country’s largest finance groups.
