In an interview with Coindesk, Deribit CEO Luuk Strijers said, "On September 27, $5.8 billion worth of BTC options expire, and there's also $1.9 billion of ETH options that will expire. Out of that, we have 20% that are in the money. When there are options that expire in the money, there is a chance that the investors will have to settle the futures or roll them over. That will definitely create some volatility in the market."
