A cryptocurrency is a digital asset designed to work as a medium of exchange that uses cryptography to secure its transactions, to control the creation of additional units, and to verify the transfer of assets. Cryptocurrencies are classified as a subset of digital currencies and are also classified as a subset of alternative currencies and virtual currencies.Bitcoin, created in 2009, was the first decentralized cryptocurrency.
Since then, numerous other cryptocurrencies have been created. These are frequently called altcoins, as a blend of an alternative coin. Bitcoin and its derivatives use decentralized control as opposed to centralized electronic money and central banking systems. The decentralized control is related to the use of bitcoin's blockchain transaction database in the role of a distributed ledger
History of Crypto
In 1998, Wei Dai published a description of "b-money", an anonymous, distributed electronic cash system. Shortly thereafter, Nick Szabo created "bit gold". Like bitcoin and other cryptocurrencies that would follow it, Bit Gold (not to be confused with the later gold-based exchange, BitGold) was an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.
The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme. In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use a script as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid. IOTA was the first cryptocurrency not based on a blockchain, and instead uses the Tangle. Built on a custom blockchain, The Divi Project allows for easy exchange between currencies from within the wallet and the ability to use personally identifying information for transactions. Many other cryptocurrencies have been created though few have been successful, as they have brought little in the way of technical innovation. On 6 August 2014, the UK announced its Treasury had been commissioned to do a study of cryptocurrencies, and what role, if any, they can play in the UK economy. The study was also to report on whether regulation should be considered.
Gareth Murphy, a senior central banking officer has stated: "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy.
Jordan Kelley, a founder of Robocoin, launched the first bitcoin ATM in the United States on February 20, 2014. The kiosk installed in Austin, Texas is similar to bank ATMs but has scanners to read government-issued identification such as a driver's license or a passport to confirm users' identities. By September 2017 1574 bitcoin ATMs were installed around the world with an average fee of 9.05%. An average of 3 bitcoin ATMs was being installed per day in September 2017.
The Dogecoin Foundation, a charitable organization centered around Dogecoin and co-founded by Dogecoin co-creator Jackson Palmer, donated more than $30,000 worth of Dogecoin to help fund the Jamaican bobsled team's trip to the 2014 Olympic games in Sochi, Russia. The growing community around Dogecoin is looking to cement its charitable credentials by raising funds to sponsor service dogs for children with special needs.

What is Crypto mining
Bitcoins aren’t printed out like traditional money, they are mined out of the system. A miner is just a person with a computer that runs a mining program on it. The reason it’s called mining is that: Just like any other natural resource, there is a finite amount of Bitcoins. So the maximum amount of Bitcoins that can be generated is 21 million. Until today over 12 million Bitcoins were mined. Just like real-world mining, you need to invest energy in order to extract these Bitcoins. The miner’s computer needs to solve complex mathematical problems, and once it solves them – new Bitcoins are generated and awarded to him.
