%{{tag.tag}} {{articledata.title}} {{moment(articledata.cdate)}} @{{articledata.company.replace(" ","")}} comment Nearly $15 billion U.S. worth of Bitcoin (CRYPTO: $BTC ) options contracts are set to expire on derivatives exchange Deribit March 27, an event that could trigger greater volatility. The options expiration represents 40% of the $36.5 billion U.S. worth of Bitcoin open interest currently on the Deribit exchange. Deribit is warning that it will see $17 billion U.S. in total options expire March 27, including both Bitcoin and Ethereum (CRYPTO: $ETH ). The options contract expirations could lead to a spike in volatility. However, there are signs that traders have been steadily de-risking ahead of the March 27 expiry. Large expiries in the past have led to big moves in Bitcoin and Ethereum that ripple across the entire cryptocurrency market. Last September, a $19 billion U.S. options expiration triggered the current downturn in Bitcoin's price, which has declined more than 40% since October. BTC is currently trading at $69,400 U.S. and has been unable to break above $75,000 U.S. in recent months.
