Brazil already has more than 180 startups dedicated to solutions and services involving cryptocurrencies, monitoring the digital currency market, we were surprised by their reported ups and downs.

The most famous of these currencies, therefore is Bitcoin, with greater acceptance and higher index of associates and investors. But what would a cryptocurrency be? How do they work and how to make investments and/or moves?

We have prepared this article especially for you who would like to enter this new financial world so flashy and promising, which by a new class that presents itself, causes and instigates many doubts in who would like to learn more about this new step of the financial world.

What are cryptocurrencies?

Extensively, cryptocurrencies are a type of money, like any other type of money we use in our daily lives. Its particularity, therefore, is that it is completely digital. And it also has no agreement or partnership with any government agency.

In order to explain convincing, Fernando Ulrich, author of the book Bitcoin: The currency in the digital age, makes a very colloquial correlation: “What the email did with the information, Bitcoin will do with money“. Before the internet age, citizens needed aides like the post office so they could deliver a message to a certain person who was distant. There was then the need to have a middleman so that they could be delivered in person. What has become obsolete even to think for people who have access e.g. to email and other messaging services.

Similarly, in some time it will be with the money, very few people use bank branches to effect their payments, or be it a bank transfer or other activities.

What are they for

As already said, so-called cryptocurrencies work the same as money, their only difference is that they are 100% digital. Its main functions are:

  • Means of exchange as facilitator of commercial transactions;

● Accumulation of value for security of future financial trading power;

● Account unit.

What is mining?

Before we talk about mining it is necessary to make it very clear that currencies like Bitcoin have a complex and change-proof encoding. Thus becoming impossible to be altered or even damaged and still falsified.

In this case there is no formalized authority to track these types of transactions, they therefore need to be recorded and subsequently validated one by one by one association of people, who use their computers to secure them on the so-called blockchain.

Blockchain is a large block of transactions, thus becoming a large public database, where all transactions made with bitcoin units are transcribed and recorded.

Each transaction made goes through this record, where it will be ensured that the same Bitcoins have not already been used by other people in other transactions.

Those who formalize these records are the so-called miners. These provide the processing power of your computers to record and verify the finalized operations with Bitcoins. In contrast they are gratified with new bitcoin units. They are created according to the thousands of computers that make up this network, and so that they solve complex mathematical problems, thus verifying the readability of the transactions included in the blockchain.

How price change works

As always, we see in force that old law of supply and demand. At a time when digital currencies gain more space and attention, it is understood that they are more requested by investors, which causes their prices to rise.

“There is only a limited number of bitcoins in circulation and new Bitcoins are created at a predictable and decreasing rate, which means that demand must follow this level to keep its price stable,” the website Bitcoin.org reports.
