A cryptocurrency is a new type of currency or digital currency that uses cryptography (advanced mathematics) and advanced computer techniques. All this in order not to depend on central entities that issue and control money.

UA cryptocurrency is a form of money or currency. P2P (peer to peer) purely digital. Being digital, it is possible to send them to any part of the world in a matter of seconds. And best of all, we can do it without the need for intermediaries like a bank. Also like any other currency, you can exchange them for goods and services. Just as we do today with traditional currencies such as the Euro or the Dollar.

So if they look so much like the money we know, Why have they created them?. Well the short answer is: These digital currencies are definitely a better form of money. In fact, they are the best form of digital money that can exist. The reasons that support this statement are the security, transparency and privacy that allow us to experiment. Features that we can experience thanks to the tecnología blockchain. And it is that a blockchain is nothing more than a database supported by a decentralized network in its entirety.

But in addition to this, the blockchain makes use of advanced asymmetric cryptography. That is, it makes use of the known public key y private key. All this in order to create a payment system that allows you to send money with a global, incensible, secure and immutable reach. This has led to a boom in the development of this technology. A situation that we can see reflected in the thousands of sites that now accept them as a form of payment.

In this sense, from Bit2Me we have set ourselves the goal of teaching you everything you should know about this form of digital money. This in order that you can know them and enjoy their benefits. To do this, we invite you to continue reading this article especially aimed at explaining everything you should know.

Cryptocurrency vs. FIAT: Which is Better?

As we said in the beginning, cryptocurrencies are a kind of digital currency, and are related to the money fiat money (traditional currencies). However, cryptocurrency and fiat money have huge differences. Among these differences we can mention the organization and control of them. In addition to the way in which value is evaluated by users.

In the case of cryptocurrencies, these are not controlled by any government or institution, they are decentralized. Furthermore, its value depends directly on the trust of the users. However, fiat money is completely opposite. It depends on the banks or the authorized central authority and governments for their operation. All this centralization allows these actors to manage these currencies at will.

Another main characteristic of cryptocurrencies is that they are crypto-based. With this, it is sought that the operations are not easily modifiable. They are also the origin of open source projects (auditable for anyone). But most importantly, your ledger (the blockchain) is made up of a huge database network. Supported by thousands of computers around the world and operating in a decentralized and consensual way.

Another great advantage is that they are open source,  anyone can access the code. With this they can develop a new cryptocurrency based on an existing one in the market. It also allows you to validate the code or detect different problems and failures. This obviously has a great impact on their safety and also guarantees that their development is maintained over time.

Some important points

  • They are not controlled / issued by any government or institution.
  • Its value depends directly on the trust of its users.
  • They are based on cryptography.
  • They are open source.
  • Your ledger is made up of a network of computers forming your blockchain.
  • Most of them have high volatility.
  • They allow financial transactions to be carried out in a decentralized manner.

Blockchain: The Heart of Cryptocurrencies

This blockchain is nothing more than a form of recording operations and totals. In it, the account of all the units of a cryptocurrency that is in circulation and all the operations carried out are kept.

Each cryptocurrency has its own blockchain, which performs the function of ledger or accounting book (among other missions). Therefore, each of these currencies has its own register, that is, its own accounting book for registering units and transactions.

This blockchain network is distributed in nature, like P2P file networks BitTorrent. There is a whole network of interconnected computers throughout the world that validates and stores the information on this network. Thanks to this there are millions of backup copies synchronizing at all times to safeguard the information instantly. Thus, the information of the creation and distribution of money through transactions, is recorded immutably. And by immutable, it is understood that its manipulation is not possible.

How much do you know, cryptonuta?

Can we use cryptocurrencies as money?


You have long been able to buy things with cryptocurrencies or exchange them for work. The only thing that differentiates them from fiat money is its technology and its decentralized nature.

The origin of cryptocurrencies

Its origin is in the 80s when the movement Cypherpunk He was betting on the use of cryptography as a means for social and political change.

In 1990 : David Chaum developed a form of digtial money called Digicash. This was electronic money centralized that allowed to carry out anonymous and secure transactions. But seven years later, Adam Back devised Hashcash based on proof of work to reduce spam and DDoS attacks. This software was the one who laid the foundations for the security and mining protocols of the cryptocurrencies of the future. Later, Wei dai would design b-money. This was a virtual currency that used a very advanced crypto mining scheme. Although this project was never completed, b-money is considered by many to be the world's first cryptocurrency.

But it was in 2008 when Satoshi Nakamotofrom whom the real identity is unknown, public the bitcoin whitepaper. This was the birth of the first fully decentralized currency, the Bitcoin. To achieve this, Nakamoto relied on blockchain technology through proof of work devised by Adam Back, using Hashcash. Thus, Satoshi proposed to use the SHA-256 algorithm, as a function hash of cryptography and a system of Proof-of-Work (PoW). Furthermore, Bitcoin was limited to an issue of just 21 million coins.

Since then, technology has caught and captured the attention of the entire world. Currently there are thousands of different cryptocurrencies, each one created in order to improve technology. However, there are few cases that have achieved this objective and reached a high audience and users. We talk about cases like Ethereum, Bitcoin Cash, Dash, EOS, Monero, Grin o ZCash. Each of these cryptocurrencies have very particular characteristics with which they seek to improve their presence throughout the world. A healthy competition that seeks to provide the best that this technology can offer in all corners of the world.

What makes them an invention without equal?

Since the invention of this type of digital money, many specialists have talked about them and their unique characteristics. One of these specialists is Jan Lansky. Lansky did a work entitled Possible State Approaches to Cryptocurrencies“, Presented in 2018 in which it describes these digital currencies in the following way:

  1. The system does not need a central authority. Thus, its status is maintained through a distributed consensus.
  2. The system maintains all units and their owner.
  3. The system defines whether new units can be created. In this case, the system must define the circumstances of its origin and how to determine the owner of the new units.
  4. You can only secure ownership of a unit to a user cryptographically.
  5. The system allows unit transactions, in which the owner of said units is changed. A transaction can only be made if the current owner of these units can be proven.
  6. If two transactions are made on the same units, the system only executes one of them.

In this series of characteristics, the nature of cryptocurrencies and those that make them what they are are enclosed. In other words, any digital currency system that meets these requirements can be considered a cryptocurrency in its entirety.

The future of cryptocurrencies

The future of cryptos is bright. Since its creation in 2008, they have gone from being a simple curiosity to being a very important global economic force. One driven by creativity and the birth of new projects and technologies thanks to the Initial Coin Offering (ICO). But not only that, they have shown that another form of economic control is possible. One where the economy does not respond to the interests and manipulations of power groups, but is completely free and decentralized. A form of economy where scourges like uncontrolled inflation have no place.

But in addition, they have also opened the doors to an economy that reaches everyone in the world. It is no longer necessary for a person to have a bank account to send or receive money. A simple cryptocurrency wallet It is enough and surplus for such a task and to manage any digital asset of this nature. This opens the doors to a true global financial revolution, of which we are only just beginning to witness. Imagine that in the future you decide to buy a car or a house. It would only be enough to access one DAPP, request a loan by guaranteeing your coins and almost instantly your loan is approved. No need for paperwork, going to a bank and huge waiting times. This is just a sample of the immense power of cryptocurrencies, the blockchain and what we can expect in the future.

But the revolution does not stop there, in fact, it is possible to imagine an even more revolutionary world. One where everything connected to the Internet can interact with others safely. One where no matter what country you live in, you can access products and services anywhere in the world and pay without complications. This is the power of cryptocurrencies. A power that tells us that their future is assured and that we are just beginning to build it. Despite this, the world of cryptocurrencies mobilizes millions of dollars daily throughout the world and continues to strengthen. This gives us an idea of ​​the current relevance of the cryptocurrency market.
