What is Cryptocurrency?

Cryptocurrency is a digital currency that can be used for transaction tools, using cryptography so that it is difficult to counterfeit. Crypto is a currency that is almost the same as dollars or rupiah, only it doesn't have a physical form, but you can still use it as a digital asset.

Cryptocurrency Functions

As a legal medium of exchange, cryptocurrencies have several functions that are now common or frequently used. Here are some cryptocurrency functions that you need to know:

1. To Buy Goods or Services

The first function of digital currency is of course as a means of payment to buy goods or services. Until now, there have been many shops or shopping places that enforce or accept this digital currency as a means of payment for the goods or services they sell, for example, Overstock and Newegg.

Apart from this, this digital currency can even be used in various restaurants, hotels, travel applications, and even now there are universities that accept this digital currency as their means of payment.

However, not all types of digital currency are accepted, so far only Bitcoin is accepted to do all of these things.

2. As a Form of Investment

The second function of digital currency is as a medium or form of investment. This form of digital money investment is more or less the same as investing in general, where when the price is low enough, you can buy it. Then after the price is going up, you can sell it again.

This digital currency is a type of investment with a fairly high risk. At the beginning of its appearance, many people suddenly became rich because they invested in this digital money by enjoying the price increases that occurred in the market. But now this form of digital money investment is not as fast as when it appeared a few years ago.

3. Mining
The next function of this digital currency is mining. Mining is a term that is based on the activity of 'mining' to get this digital money asset. The term refers to activities to solve the cryptocurrency puzzle to enhance cryptocurrency assets.

To solve the puzzle is not easy, you need a lot of computing power. The more computing power you have, the greater your chance to solve the puzzle.

How Cryptocurrency Works

Cryptocurrency can be said to be a means of payment that is almost the same as a means of paying physical money today. The difference is that for this currency there is no central party that regulates the amount of circulation of this currency.

This is because the way this digital currency works is that when a transaction occurs using cryptocurrency, the transaction will produce cryptographic evidence that has been verified and recorded in the blockchain.
