The sudden push to a fresh all-time high in Bitcoin over the weekend has options traders adding to bets that the largest cryptocurrency will rally to $140,000.

Short-term Bitcoin options contracts that settle toward the end of the year have seen open interest clustered around that strike price for calls, according to data from crypto derivatives exchange Deribit by Coinbase. There has also been a moderate increase in demand for puts, as traders seek downside protection from a pullback after the rally.
