Cryptocurrency is a digital or virtual currency that uses cryptography for security. A cryptocurrency is difficult to counterfeit because of this security feature. A defining feature of a cryptocurrency, and arguably its most endearing allure, is its organic nature. It is not issued by any central authority, rendering it theoretically immune to government interference or manipulation.
Cryptocurrencies use decentralized control as opposed to centralized digital currency and central banking systems. The decentralized control of each cryptocurrency works through a blockchain, which is a public transaction database, functioning as a distributed ledger. Bitcoin, first released as open-source software in 2009, is generally considered the first decentralized cryptocurrency. Since the release of bitcoin, over 4,000 altcoins (alternative variants of bitcoin, or other cryptocurrencies) have been created.
Cryptocurrency security risks can be categorized into three main areas: exchanges, wallets, and transactions.
Exchanges
Cryptocurrency exchanges are online platforms that allow users to buy, sell, and trade cryptocurrencies. Exchanges are a convenient way to access the cryptocurrency market, but they also pose a number of security risks.
One of the biggest risks associated with exchanges is hacking. Hackers have been able to successfully breach a number of exchanges, stealing millions of dollars worth of cryptocurrency. In 2014, for example, Mt. Gox, one of the largest cryptocurrency exchanges at the time, was hacked and lost over $450 million worth of bitcoin.
Another risk associated with exchanges is fraud. There have been a number of cases where exchanges have been accused of running scams or engaging in other fraudulent activities. In 2016, for example, Bitfinex, another large cryptocurrency exchange, was accused of covering up a $850 million loss.
Wallets
Cryptocurrency wallets are software programs that allow users to store their cryptocurrency. There are two main types of wallets: hot wallets and cold wallets.
Hot wallets are connected to the internet, which makes them more vulnerable to hacking. Cold wallets are not connected to the internet, which makes them more secure. However, cold wallets can be more difficult to use and may require additional fees.
Transactions
Cryptocurrency transactions are recorded on a public ledger called a blockchain. This makes it possible for anyone to track transactions, which can make users vulnerable to identity theft and fraud.
In addition, cryptocurrency transactions can be irreversible, which means that if you send cryptocurrency to the wrong address, there is no way to get it back.
