What you need to know about cryptocurrencies

Cryptocurrencies are virtual coins, thus, they are digital money. But we must not mix up these three terms up. Not all virtual coins are cryptocurrencies, and neither is all digital money cryptocurrencies. It does apply the other way around, though.

It’s all about “decentralized money where you don’t need a bank, it’s not issued by any government, it’s fast and almost free to transfer value”, ámbito.com affirms. One of its characteristics is its volatility, with daily fluctuations.

How to earn cryptocurrencies or invest in them?

As every other business, you must analyze the market before investing. First, I recommend you select a wallet to keep your cryptocurrencies in.

After, you must choose a platform to handle them or a cryptocurrency Exchange, which is the place where you buy, sell or change cryptocurrencies for another digital currency or for “real” money like dollars or euros. There are exchanges that offer their own wallet.

I suggest you verify the security, the reputation, geographical restrictions, exchange rates and methods of payment before you choose. Make sure to choose trustworthy wallets and Exchanges like Coinbase, Binance, Cex.io y Bittrex.

There are ways to make money for free on the Internet with cryptocurrencies. For this, you must store them in your digital wallet and then spend or change them for conventional money. You could also get cryptocurrencies by buying them.

If you wish to buy cryptocurrencies, do it for the lowest price possible and wait until the price has risen to sell them so that you get a profit.

Some advantages and disadvantages of cryptocurrencies.


  • They are global coins, which allows you to use them anywhere in the world.
  • Their transactions are irreversible: no third-party can cancel or modify a transaction, which they already made.


  • They are not backed up by any government or bank, which means that no digital wallet has the same protection that bank deposits have.
  • Their value is unstable; it changes very quickly which means it’s a highly risky business.

Risks of investing in cryptocurrencies.

Do you wish to invest in cryptocurrencies? You should know the risks and signs of a possible scam, that the website of the Federal Commission of Commerce of United States has stated.

  • No one can guaranty you actually win money. Anyone that assures you a profit is probable a swindler. Remember not to invest what you’re not willing to loose.
  • Not all cryptocurrencies-or companies that promote them- are the same. You must always research the name of the company and/or cryptocurrency in question, using the terms “review”, “scam” or “complaint”. Something like fact checking.
  • Cryptopirating: It happens when somebody scams you by using processing power on your computer or smartphone by “minning” cryptocurrencies in their benefit. You can detect it when your device is working slower than usual, if your battery is frequently low or if it collapses. To avoid it, make sure you keep your antivirus software updated and don’t access links to untrustworthy or unknown websites.

Leaves, a new and attractive concept

Banks are secure places in which unjustified fluctuations aren’t conceived in your bank accounts. Nonetheless, the value associated to your account is still a number somewhere. A number that, theoretically, could be altered.

Cryptocurrencies add an extra layer of security. By being a decentralized system, every account or wallet is not summed up in a number stored somewhere but is saved in each of the cryptocurrencies’ minners’ device. To be able to alter this number, you would need to hack a great deal of the network, computer by computer, phone by phone.

FySelf, the first social identity network, recognizes these potentialities and is willing to use them to guaranty the security and transparency of the monetary value. For this reason, it created an alternative that links the security of cryptocurrencies and the stability of banks: the leaf.

FySelf’s leaf represent the value of personal data
The leaf possesses every advantage that the cryptocurrencies have. Nonetheless, there isn’t a market to be able to buy the, these are obtained in a transparent manner during the interaction with FySelf. It has an exchange rate with the euro which is verifiable at every moment.

The leaves are an accumulative value that represents the value of the personal data of each user before they can extract it. The amount grows from the quantity of information that the user decides to use or decreases if the user decides to withdraw it. Something very similar happens with a conventional bank account.

The world of cryptocurrencies is fascinating. If you want to relate it to the value of your personal data, stay tuned for the launch of the first social identity network.
