币界网报道：According to the data of Deribit, a cryptocurrency options trading platform, a trader paid more than $2 million in premium on Thursday to buy 61,000 Ethereum call options with strike prices of $3,200 and $3,400, expiring at the end of June. In theory, buying a $3,200 call option is a bet that the price of Ethereum will rise from the current $2,460 to more than $3,200 at the end of the month. Buying a $3,400 call option indicates that the price is expected to break through this level. In other words, the trader expects the price of Ethereum to rise by more than 30% in three weeks. Call options give buyers the right (not obligation) to buy the underlying asset at a predetermined price in the future. Call option buyers are usually bullish on the market and pay a premium to obtain asymmetric gains. In this case, the $2 million premium is the maximum amount the buyer could lose if the market does not rise as expected.
