Bitcoin and BitShares are two different things.
Bitcoin is a cryptocurrency and a payment system, first proposed by an anonymous person or group of people under the name Satoshi Nakamoto in 2008. BitShares is a decentralized exchange and asset platform, founded by Daniel Larimer in 2014.
BitShares is not part of Bitcoin. It is a separate distributed ledger technology platform that uses its own cryptocurrency, BTS. BitShares is a decentralized, autonomous organization (DAO) with its own blockchain, consensus mechanism, and token system. It is not associated with Bitcoin in any way.
Investing in or using Bitcoin and BitShares carries significant risk and should be done with caution after researching both technologies thoroughly.
BitShares is built on top of the Graphene blockchain, which is an open-source project created by the BitShares community. Graphene can process transactions up to 10,000 times faster than Bitcoin.
BitShares also has its own native currency, called BTS. BTS can be used to trade assets on the BitShares platform or used to pay for transaction fees.
So, while Bitcoin and BitShares are both decentralized and use blockchain technology, they are two different projects with different goals.
