海角社区

A cryptocurrency is a virtual or digital currency which uses complex algorithms to make it possible to conduct secure digital transactions. The common characteristics in all cryptocurrencies are the use of cryptography for security and their decentralized control system so that there is no single centralized authority to issue the currency. The Bitcoin was the first successful decentralized cryptocurrency and became the inspiration of many other cryptocurrencies used all over the 海角社区.

Auroracoin

The Auroracoin is a cryptocurrency used in Iceland as an alternative to the traditional Icelandic krona. The Auroracoin (abbreviated as AUR) was released to the public in 2014 as a result of government restrictions placed on the Icelandic krona with the international movement of the krona being severely restricted. The auroracoin was issued freely to the public in a process known as 鈥渁irdropping,鈥� conducted in three phases. In its inaugural issue, each claimant received 31.8 auroracoins with each auroracoin being valued at $12.11. The Icelandic government has mixed feelings about the auroracoin with politicians seeing it as way individuals can exploit to evade taxation. However, during phase one of the issuance of the cryptocurrency, the government allowed the developers known as Odinsson to use the national database of citizens to identify claimants of the cryptocurrency.

Bitcoin

The Bitcoin is another form of digital currency which is synonymous with the cryptocurrency. Issued in 2009, the Bitcoin was the first cryptocurrency to be issued for wide-scale transactions.

The Android wallet was created to supplement the existing PC Burst Wallet.

Coinye

The Coinye is a defunct digital currency issued internationally between January 2014 and May 2014. The crypt-based currency was developed by David P. McEnery Jr. The Coinye was originally known as Coinye West, named after American rapper, Kanye West and used the rapper as its mascot. The cryptocurrency鈥檚 logo also featured a half-fish, half-human figure whose face closely resembled Kanye West. The move prompted the rapper to file a lawsuit against the developers for trademark infringement. After being engaged in the legal tussle, the developers of the Coinye abandoned the project, and Coinye is no longer active.

Unlike most cryptocurrencies, the Dogecoin has a fast initial coin production schedule with the 100 billionth Dogecoin being mined on June 30th, 2015 and 5.256 billion coins every year after that. In December 2015 Dogecoin experienced its first theft attempt with millions of coins being stolen through hacking of its Dogewallet platform.

Criticism Of Cryptocurrencies

The most widespread concern people have about cryptocurrencies is the safety and legality of the virtual currencies. Almost all the major cryptocurrencies have been targeted by hackers which led to the theft of millions of digital coins. Very few financial institutions around the 海角社区 allow cryptocurrency transactions. Due to the factor of anonymity, cryptocurrencies have become the preferred mode of payment for illegal transactions conducted through the Darknet markets.
