A crypto currency is a digital or virtual currency that uses cryptography to secure, create and control its transactions. Unlike traditional currencies, which are issued by central banks, crypto currency has no central monetary authority. Bitcoin is the first crypto currency which came to public notice in 2009. Following this a number of other crypto currencies, such as Ethereum, Ripple, Litecoin, Cardano etc. exist in the market. Crypto currency can be exchanged for other currencies, products, and services. In recent months, Economists, Central Bankers and Monetary Experts have expressed their reservations on the future of this currency. Investors and Enthusiasts of this currency are however bullish.
How does a Crypto Currency work?
The technology behind Crypto functioning is Blockchain. A blockchain is a public ledger that keeps records of all prior bitcoin transactions. These data units or blocks use cryptographic validation to link themselves together. The entire network is used to monitor and verify both the creation of native tokens through mining, and the transfer of tokens/coins between users.
Miners are individuals or organizations who, with the use of powerful computers carry out mining process. Mining is the process by which transactions are verified and added to the public ledger, block chain, and also the means through which new coin are released. The mining process involves compilation of recent transactions into blocks and finding solution of a computationally difficult puzzle.The successful miners who solve the puzzle get to place the next block on the block chain and are rewarded. The reward is twofold. The newly minted tokens/coins and the fees paid by users sending transactions are rewarded to the miners for their efforts.
Advantages:
As a decentralized currency, Crypto currency cannot be manipulated by governments and central authorities of any country. Also because of its decentralized nature it is inflation averse.
Unlike bank transactions, Crypto transactions are completely anonymous. A person can only know the addresses of crypto on which the payment has been sentand received. But to whom these addresses belong cannot be identified.This anonymity feature offers security against fraud and identity theft.
Due to dramatic rise in its popularity among the masses it is gaining wide acceptance as a payment method.
The fee for crypto transactions is relatively low as compared to other digital transactions such as credit cards and other modes.
The mechanism behind crypto generation is highly complex which prevents duplication or creation of fake currency.
Disadvantages:
A highly volatile nature, huge price change over a short period, of crypto poses a serious question to consider it as a future currency.
With government of different countries having different attitudes towards considering crypto currency as a legal tender, people unaware of its mechanism consider it to be a risky investment.
The anonymous nature of crypto transaction attracts its usage for illegal and illicit activities such as tax evasion, weapons procurement, gambling etc.
Crypto transactions are irreversible in nature. Funds sent to a wrong address cannot be traced back and result in loss of all the transferred money.
If the storage device in which crypto currencies are stored gets damaged or lost. Then the lost Bitcoins cannot be recovered by any means.
Cases of online hacking of crypto exchanges such as Mt. Gox in Japan, Bitfloormake etc.make it more risky.
