What Is Cryptocurrency?

Cryptocurrencies are encrypted decentralised digital currencies that are transferred between individuals. These currencies are not tangible and exist only in the electronic from, it is a digital asset that exists and remains as data.  They allow a person to send money just like sending an email, much lower transaction times compared to using a bank, minimal fees, no credit cards and no middleman.

The joint bookkeeping process is called a “Blockchain”, it is public and is distributed across the network of all the people that have the same coin, for example everybody that has Bitcoin has a copy of the ledger and its transactions, which creates a community of trust. Each cryptocurrency is individually identifiable and programmable based on a very complex digital code.

Breaking Down Cryptocurrency

Cryptocurrencies are systems that allow for the secure payments of online transactions that are denominated in terms of a virtual “token,” representing ledger entries internal to the system itself. “Crypto” refers to the fact that various encryption algorithms and cryptographic techniques, such as elliptical curve encryption, public-private key pairs, and hashing functions, are employed.

The first cryptocurrency to capture the public imagination was Bitcoin, which was launched in 2009 by an individual or group known under the pseudonym, Satoshi Nakamoto. As of February 2019, there were over 17.53 million bitcoins in circulation with a total market value of around $63 billion (although the market price of bitcoin can fluctuate quite a bit). Bitcoin’s success has spawned a number of competing cryptocurrencies, known as “altcoins” such as Litecoin, Name coin and Peercoin, as well as Ethereum, EOS, and Cardano. Today, there are literally thousands of cryptocurrencies in existence, with an aggregate market value of over $120 billion (Bitcoin currently represents more than 50% of the total value).

Bitcoin Facts

There will only ever be 21 million bitcoins.

At present, 16.3 million have already been mined and are being traded. The last bitcoin will be mined in 2140. After that, no new bitcoins can be mined.

Bitcoin can’t be banned.

The fundamental design is such that it can’t be banned, only regulated. As long as you have an internet connection and a Bitcoin wallet, you can engage in Bitcoin.

The inventor of Bitcoin is a mystery.

The Bitcoin whitepaper was made open to the public under the pseudonym of Satoshi Nakamoto. The identity of “Satoshi” is still a mystery yet to be solved.

Understanding cryptocurrency properties

1) Irreversible: After confirmation, a transaction can‘t be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net.

2) Pseudonymous: Neither transactions nor accounts are connected to real-world identities. You receive Bitcoins on so-called addresses, which are randomly seeming chains of around 30 characters. While it is usually possible to analyze the transaction flow, it is not necessarily possible to connect the real world identity of users with those addresses.

3) Fast and global: Transactions are propagated nearly instantly in the network and are confirmed in a couple of minutes. Since they happen in a global network of computers they are completely indifferent of your physical location. It doesn‘t matter if I send Bitcoin to my neighbor or to someone on the other side of the world.

4) Secure: Cryptocurrency funds are locked in a public key cryptography system. Only the owner of the private key can send cryptocurrency. Strong cryptography and the magic of big numbers makes it impossible to break this scheme. A Bitcoin address is more secure than Fort Knox.

5) Permissionless: You don‘t have to ask anybody to use cryptocurrency. It‘s just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or other cryptocurrencies. No one can prevent you. There is no gatekeeper.
