What is the value of money? What is its true price? Cryptos operating outside the regulation of governments, generate an alternative financial system: with offers and demands, without physical printing, with transparency and a particular logic.

While money is monopolized by governments and financial institutions in each country, the most important cryptocurrencies (Bitcoin, Ethereum) are based on a limited supply, so they tend to conserve and increase their value.

Its security is shielded by a mathematical encryption and by a chain of blocks in which each of the transfers in cryptocurrencies is tied by the next. So the whole system depends on itself. Then the counterfeiting process disappears. Authenticity is granted by users (guaranteed by the blockchain) and not by banks, insurance companies, or currency exchange agencies. So, then, digital currencies have practically no transaction fees: they clear those agents from the business. And, unlike the traditional system, they maintain the confidentiality of transactions.

In their logic, cryptocurrencies, which are declared enemies of the financial and tax systems, represent two ideals: equality and security. It does not matter the country, nor the nationality, nor the sex, nor any external factor that could alter the power of the currency. Simply put, cryptocurrencies are spoken of as a decentralized peer-to-peer exchange system.

Having the opportunity to understand how each of these resources circulates and to be able to program their rules of use once they are disbursed opens the doors to sophisticated economic decisions.
