After reviewing Ether (ETH) options for June 25, one might think that traders either became overly optimistic or ultra-bearish. Currently, there are large bets for prices below $1,000 while others aim for $3,800 and higher.A recent report from Coinshares shows that multiple crypto funds have begun seeing net inflows after weeks of record outflows. The report notes that Ether vehicles saw a total of $47 million in inflows, bringing its market dominance up to 27%.DeFi growth supports higher Ether pricesAnother positive factor is that DeFi protocols maintain a $48 billion total value locked (TVL) even though the sector took a substantial hit after the recent Ether price crash.Ethereum network net value locked on smart contracts.

Therefore, as Ether dropped from the $4,380 all-time high on May 12, traders quickly scrambled to set up protective puts down to $400.On the other hand, the much-anticipated transition to a proof-of-stake consensus model could be the root of the positive expectations. The EIP-1559 improvement proposal set for next month is another significant stepping stone, and some traders have price targets ranging from $4,000 to $10,000.June 25 Bitcoin options open interest. Source: BybtThere are currently 623,800 Ether option contracts expiring on June 25, totaling a $1.75 billion open interest. The neutral-to-bullish call (buy) options are currently 29% more represented, although this call-to-put ratio uses an equal weight for every strike regardless of its probabilities.Bears spent over $1 million building their positionsThe ultra-bearish put (sell) options at $1,600 and lower amount to 170,000 Ether contracts, amounting to a $476 million open interest. However, considering the roughly three weeks left until the June 25 expiry, those contracts are trading below $32 each. The market value for those bearish options stands at $1.2 million.On the other hand, bulls likely have exaggerated by buying call options at $3,800 and higher. These 160,000 Ether contracts amount to a $450 million open interest but considering that their current face value is below $80 each, their market value stands at $5 million.Therefore, bulls spent more money setting up their position despite the similar open interest placed on both sides. These out-of-the-money options are an excellent way for options sellers to cash in the premium in advance. The same methodology can be applied for $2,100 put options and $3,800 call options.The views and opinions expressed here are solely those of the author and do not necessarily reflect the views of Cointelegraph.
