A Centralized Exchange would be the @NYSE where all Exchanges including Over the counter and ATS have to report to the @NYSE Consolidated tape. 

Vs

A Decentralized Exchange which is Governed by a Smart Contract which controls a Ledger on a Blockchain. 
Where your trading with actual fuckn people and algorithm is facilitating the transaction. Not a fuckn human who can be geared towards corruption. 

Blockchains holding ledgers of customers accounts and Smart contracts governing those blockchains is the future of financial technology. 

Having Folks tokenize their assets like the title of their Cars , houses and other property into a token and stored and traded on a decentralized exchange. 

Decentralized Finance is the Future and Bitcoin introduced the First Blockchain to ever be made with an immutable ledger. Meaning No mutha fucker can touch the ledger and alter it and it’s all public.
