The trader bought call options when Bitcoin was close to $68,000 and bought put options when it was near $66,000

Yev Feldman, co-founder of SwapGlobal, which provides derivatives such as swaps and options to U.S. digital asset investors, said, "We see traders buying call options when it's close to $68,000 and put options when it's near $66,000. In other words, many people are constantly adjusting their positions for Bitcoin to further break through both ends. However, there is limited reason for the significant drop in Bitcoin after the U.S. presidential election so betting on a rise makes more sense."
