Options are financial instruments that are derivatives based on the value of underlying securities such as stocks, commodities, foreign exchange or cryptocurrency. An option contract offers the buyer the right but not the obligation to buy or sell—depending on the type of contract they hold—the underlying asset, while the sellers are obliged to buy or sell if the option expires in-the-money. Unlike futures, the holder is not required to buy or sell the asset if they choose not to. Traders buying option contracts, either call or put options, are called option buyers or option holders, while those who sell them are called option sellers or option writers. Read more>
Options can be divided into European and American options according to the method of execution. If the option can only be executed on the expiration date, it is called a European option; if the option can be executed at any time on and before the expiration date, it is called an American option.
According to the type of purchase and sale, options can be divided into call options and put options.
A call option is the right to "buy the underlying asset" at the strike price on the expiration date. The buyer of a call option bets on an increase in the price of the asset.
A put option is the right to "sell the underlying asset" at the strike price on the expiration date. The buyer of a put option bets that the price of the asset will fall. Read more>
Bit.com options are European-style options contracts on cryptocurrencies, allowing users to buy or sell cryptocurrency options and exercise on the expiration date.
As the buyer of the option, the user need to pay the seller a premium when buying the option, and bit.com will automatically exercise or not exercise the option for the buyer on the expiration date based on the price of the underlying asset.
As the seller of the option, the user will receive the premium paid by the buyer, and meanwhile will be required to pay a portion of the margin as a guarantee when selling the option. In addition, the option seller will be required to cooperate with the execution or non-execution of the contract on the expiration date, and the system will release the account margin of the seller if there is no need to exercise the option on the expiration date.
The options products of Bit.com are classified into coin-margined options and USD-margined options according to the denomination and settlement currency.
Currently, Bit.com supports three types of coin-margined option products: BTC, ETH and BCH.
Also, Bit.com supports two types of USD-margined option products: BTC and ETH.
Trading fee (Coin-margined option)= position size * fee rate
Trading fee (USD-margined option)= position size * index price * fee rate
Maker Fee: 0.02%
Taker Fee: 0.05%
Note: Taker/Maker Fee cannot be higher than 12.5% of the option value.
Delivery fee (Coin-margined option) = position size * fee rate
Delivery fee (USD-margined option) = position size * delivery price * fee rate
Delivery fee rate:
0% for daily options
0.015% for all other options (Delivery fee cannot be higher than 12.5% of the option value)
Forced liquidation fee
Forced liquidation fee (Coin-margined option) = position size * fee rate
Forced liquidation fee (USD-margined option) = position size * index price * fee rate

The liquidation fee after subtracting trading fee will be automatically allocated into the Bit.com insurance fund.
