On Friday, Aug. 13, a total of $675 million worth of Bitcoin (BTC) options are set to expire, and currently the bulls enjoy a significant advantage after a 20% weekly rally to $46,743. 

As Cointelegraph previously reported, two things that marked the positive shift seen from institutional investors were that deposits to derivatives exchanges reached their lowest levels since May 11 and that entities with 10,000 to 100,000 BTC added over $12 billion additional Bitcoin to their holdings.

Meanwhile, cryptocurrency adoption continues to rise as the Paypal-owned payments firm Venmo has expanded its support by allowing credit card holders to convert their cash back rewards into four cryptocurrencies.

Investors could also be reacting to the new wave of indirect exposure exchange-traded fund (ETF) filings with the United States Securities and Exchange Commission. The latest request came from the asset manager VanEck on Aug. 10.

BitMEX’s $100 million settlement and ETF hopes fueled the bullish bets

On Aug. 3, SEC Chair Gary Gensler hinted that it would be more open to accepting a BTC ETF application if specific changes were made to the instrument.

This week, BitMEX also agreed to resolve a case from the United States Commodity Futures Trading Commission and the Financial Crimes Enforcement Network. As part of the settlement, BitMEX will pay up to $100 million in civil monetary penalties "for illegally operating a cryptocurrency trading platform and anti-money laundering violations."

This newsflow helped to fuel some bullish bets for Friday's options expiry, but some traders became overly excited.

The total figure is similar to the previous week's $625 million options expiry, which also had a 1.78 call-to-put ratio at the time. This week, the neutral-to-bullish call options dominate again and the protective put options are below the current $46,500 price level.

If Bitcoin remains above $46,000 on Aug. 13 at 12:00 pm UTC, all of the 5,278 BTC put option contracts will be worthless.

On the other hand, only 5,335 BTC call (buy) options will take part of the expiry, and this is equivalent to $245 million. Investors got overly excited, buying $48,000 and higher bullish options, which reduced the $435 million potential of these call options.

Bears place their dreams on a sub-$44,000 Bitcoin price

Bulls could use their significant advantage to force the price upward, as reaching the $48,000 mark would increase the options expiry notional by $80 million. In this case, the bulls' upper hand would reach $325 million and display an even stronger dominance over the market.

The only solution for the bears lies in an improbable expiry below $44,000. This would drastically reduce the bulls' advantage to a meager $80 million if it somehow happens on Friday.

Although it might be too early to call the race, the incentives for moving the price of Bitcoin 5% below $46,500 do not seem worth the effort.
