The ORIGIN OF CRYPTO CURRENCY

   

Ten thousand Bitcoin for two large pizzas.

The concept may sound insane now, yet this is considered the first real-world Bitcoin transaction in history.

The first time Bitcoin, which is currently worth $10,000 USD each piece, was used to buy anything physical occurred on May 22, 2010, now known as "Bitcoin Pizza Day."

Satoshi Nakamoto (a cryptography pioneer who illustrated how digital currencies may pose a challenge to central banks.) published the white paper Bitcoin - A Peer to Peer Electronic Cash System on October 31, 2008, detailing the operation of the Bitcoin blockchain network.

Satoshi formally started working on the Bitcoin project on August 18th, 2008, when he bought Bitcoin.org.

This first block of 50 Bitcoins is now referred to as the Genesis Block which was the first instance of a proof-of-work blockchain(Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business 
network.) system and is the template for all other blocks in its blockchain. 

Bitcoin had almost no value.

And today  the cost is more than 20,000 USD
