Crypto call options explained

A crypto call option is a contract giving its buyer the right, but not the obligation, to buy a cryptocurrency at a fixed strike price before an expiration date. The buyer pays a premium for the right. A call pays when the coin’s price finishes above the strike price, and the premium is the most the buyer can lose, however far the coin falls. For example, a $100 call bought for $10 pays $30 at $130, a $20 profit.

When does a crypto call option make money?

A crypto call option makes money when the coin’s price rises above the strike price by more than the premium. First, a call option “gives its buyer the right, but not the obligation, to buy an agreed quantity” of the asset at the strike price, according to Wikipedia’s entry on call options, and the seller must sell if the buyer exercises. Second, the payoff at expiry is the gap between the coin’s price and the strike price, or zero if the coin is below the strike. Third, the break-even point is the strike price plus the premium. For example, with a $100 strike price and a $10 premium, the call breaks even at $110: a coin price of $130 at expiry pays $30, a profit of $20 after the premium, 2 times the premium paid; a coin price of $105 pays $5, a loss of $5; and a coin price of $100 or below pays nothing and loses the whole $10 premium.

What is the most a call option buyer can lose?

The most a crypto call option buyer can lose is the premium paid for the call. First, the premium is paid upfront and is the whole stake; according to Binance Academy, “the premium is the most you can lose as a buyer of an option,” and the rule holds when the coin halves or the option expires worthless. Second, the risk sits with the call seller, not the call buyer: Binance Academy warns that selling a call without owning the coin carries significant risk if the price rises sharply, because the seller has to deliver the coin at the strike price whatever the market price is. Third, the whole premium is lost often. A call needs the coin to climb past the strike price plus the premium, so a coin drifting sideways or rising too slowly leaves the call out of the money. For example, a $10 premium on a $100 call is lost with the coin at $100, at $90 or $50.

How do call options work on Supervega?

Supervega is a crypto options app where every option is a call: the seller locks crypto in a smart contract first, so the payout is pre-funded. First, pick an asset and set a target price: the target price plays the role of the strike price. Second, set a deadline: the deadline is the expiration date. Third, pay a small fee upfront: the fee is the premium, and the fee is the most a Supervega buyer can lose, with no liquidations and no margin calls. Supervega ranks the available options for the chosen target and deadline by multiplier, where the multiplier is how many times the fee the buyer receives if the price reaches the target; for example, a $10 fee with a multiplier of 5 pays $50, 5 times the fee. If the asset hits the target price before the deadline, the payout is sent to the wallet automatically, and above the break-even price a partial profit can be claimed early from the portfolio.
