A greeting Steemit community, today I come with a very interesting post, I will talk about a subject in which we must all be submerged, since this has been shaking and giving of what to talk in recent years when economics and finance is . No more to add, make it comfortable that cryptocurrencies are to rule our economic system.

What are cryptocurrencies?

It is a digital currency, which can be easily exchanged. They are implementing a safe, reliable and anonymous economy. Bitcoin was the first cryptocurrency that began operating, created in 2009 by a group of people under the pseudonym Satoshi Nakamoto.

Since then, a lot of cryptocurrencies have emerged, which have been gaining acceptance, interest and confidence from millions of people in the world. Attention to trust, is a key word and plays a very important role here, something I highlighted, but there is nothing to worry about, I will explain later.

How can I get Bitcoins?

I know two ways in which you can get Bitcoins. The first, and simplest, is to access the Bitcoin markets, one of which I know is: Localbitcoins.com, this platform allows you to buy and sell Bitcoins, using conventional money, dollars or euros. I recomend it to you

Another way to get Bitcoins is through the mining method, yes, you read well, the method of mining. This consists of using part of the resources of our computer, in order to solve extremely complex mathematical problems. This method is very interesting and somewhat profound.

Advances of mining.

Initially, mining focused on using the speed of your CPU (Central Processing Unit). It was not necessary to have equipment specially dedicated to it, simply any user could download software on their computer and start mining. This method of mining had a very easy degree of difficulty, because at first the transactions of Bitcoins were very low, not everyone trusted in the cryptocurrencies. Attentive, the word confidence returns to appear!.

As time progressed, mining began to consume much more resources, so it was no longer profitable to use the CPU, therefore, it began to focus on the GPU (Graphic Processes Unit), these are graphic cards mostly used in the world of video games. The ability to mine with a GPU was very cost effective and consumed fewer resources.

Currently, the most profitable mining is governed by the ASIC (Integrated Application Specific Circuit) cards, which were created specifically for mining. They are very expensive equipment, making acquisition of it very complicated.

Are cryptocurrencies reliable?

This question has been asked by many people who have thought about starting a project where cryptocurrencies are the protagonists. For a user with low economic resources it would be very difficult to acquire, for example, 1 Bitcoin, since its value is around $ 11,000, lastly it has come down in a brutal way. Even though the price of Bitcoin is high, investing in this crypto is very reliable.

Every day millions of users invest in Bitcoin with "eyes closed", what is its reliability? Well, friends, as I said a few paragraphs ago, reliability is a keyword and this is generated because a lot of people are investing in cryptocurrencies, especially in Bitcoin. In addition, Bitcoin is known throughout the world, that is, you know a lot of information about it, and... Do you know what this means? Information generates trust, and the more we know about something, the more confidence we have in it and thus we can acquire it without any doubt.

The cryptocurrencies will change the financial system, the banks of different countries will have to study to be able to take out their own cryptocurrency and not stay in the "apparatus", since the profitability of the crypto in recent years has been impressive. Remember, everything is summarized in the confidence of the same.
