Deribit Bitcoin Options Expire
About $11 billion in Bitcoin options expire on Deribit, a crypto options exchange, with Bitcoin trading near $81,500. The options cover about 135,000 Bitcoin, with a put-to-call ratio of 0.52 indicating more calls than puts. The $11 billion is notional value, not money changing hands, and about 86% of the contracts are out of the money, meaning they would be worthless at current prices.
