Yes, you can buy call options on Ethereum.
Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of fraud or third party interference.
Ethereum is used to build decentralized applications (dapps) on its blockchain. A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as “completed” blocks are added to it with a new set of recordings.
Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
There are two types of options: calls and puts. A call option gives the holder the right, but not the obligation, to buy an underlying asset at a specified price on or before a specified date.
A put option gives the holder the right, but not the obligation, to sell an underlying asset at a specified price on or before a specified date.
The value of an option contract depends on many factors, including the price of the underlying asset, the strike price of the option, the time remaining until expiration, and implied volatility.
