Advantages and disadvantages of an "inspiring" currency

After learning about mining last week, you are probably wondering what the overall advantages and disadvantages of cryptocurrencies are.

Over the last couple of years the term cryptocurrency has been rapidly gaining the public eye. Just a simple google trend search shows you the start of the growth.




However, what are the advantages and disadvantages of this “inspiring” currency?

Advantages:

  1. Ultra Secure and inexpensive to secure. First of all, payments using cryptocurrency can be made and finalized without one’s personal information being tied to the transactions. Moreover, due to the fact that personal information is kept hidden from prying eyes, cryptocurrencies protect against identity theft. Last but not least, cryptocurrencies can be backed up and encrypted to ensure the safety of your money.
  2. The supply is controlled and capped.
  3. Concerning fraud, it is practically impossible to counterfeit. Cryptocurrency use a “push” mechanism that allows the cryptocurrency holder to send exactly what he or she wants to the merchant or recipient with no further information.
  4. One of the benefit of cryptocurrency vis-a-vis current fiat currencies is that the central bank can’t take it away. Cryptocurrencies are decentralized. In other words, YOU own it. You own the private key and the corresponding public key that makes up your cryptocurrency address.
  5. Freedom in payment. With cryptocurrencies, it is very possible to be able to send and get money anywhere in the world at any given time.
  6. Information is Transparent. With the blockchain, all finalized transactions are available for everyone to see, however personal information is hidden. For instance, Bitcoin protocol cannot be manipulated by any person, organization, or government. This is due to Bitcoin being cryptographically secure.


Disadvantages:

  1. Lack of awareness and understanding. Many people are still unaware of digital currencies. These people need to be educated about it to be able to use it and apply it in a right way to their lives.
  2. Cryptocurrencies are volatile due to the fact that their supply is limited and their demand is increasing day by day. However, this volatility is expected to decrease with time because, as more businesses begin to accept these cryptocurrencies, their prices will begin to settle down.
  3. Still in development. Cryptocurrency is still in its infancy stage; a lot of its features are still in development. The full potential of these currencies has not be reached yet…


Conclusion:

To sum up, cryptocurrencies have a long way to go before they can replace credit cards and traditional currencies as a tool for global commerce. A survey done by PWC in 2015 shows that only 6% consider themselves very familiar with cryptocurrencies. However, and in order to finish this article with a positive note, we can say that cryptocurrencies could be seen as the 2.0 version of gold…

What Is Mining?

Understanding the Concept

Mining is an essential process for the creation of new cryptocurrencies. It is a special software that uses computer power to solve mathematical problems, allowing miners to verify transactions and add them to the public ledger, the blockchain. As a result, new cryptocurrencies are issued and miners are rewarded for their work. 

Importance of Mining

Mining was developed to create and validate transactions, consequently the most important aspect is security. For the process to be complete, it needs to be verified by other miners, to assure the legitimacy of it. So, by getting more people involved in the systems it increases the security and makes it more difficult to subvert or corrupt the network.


How Does It Work?


The mining process requires a Proof-of-Work, which is a method to ensure that the information (the new block) was difficult (costly and time-consuming) to be made. Miners need resources: hardware, energy and time to complete the procedure.



Mining Evolution

In the beginning, there were a few people involved in the mining ecosystem, which allowed miners to use their own computers and laptops to complete the transactions. However, with the reward and incentives, the competition expanded and the process became more complex. The mathematical problems increased difficulty, forcing miners to use more resources and more efficient hardware to verify the same amount of information (here is an example of the bitcoin difficulty chart throughout the years).

Nowadays, the mining process is well developed and miners cooperate and work in mining pools, which are groups of people who agree to share block rewards in proportion to their contributed mining hashing power. Additionally, they realized that to gain competitive advantage, cheap electricity and special hardware were important factors to succeed.

In the latest Techcruch’s video, we can observed how this business has grew, and how China has become one of the main countries doing it. Here, miners can meet all the conditions to be the most efficient players in the system, creating huge installations around the country, where the majority of the cryptocurrencies are currently mined.

Exclusive Interview with Xapo CFO Félix Moreno

What is Xapo doing?

Xapo was founded by serial entrepreneur Wences Casares in 2014 with the intention to safely store Bitcoins. Furthermore, Xapo offers the use of a debit card for an underlying Bitcoin account that can be used everywhere Visa is accepted.   


Who is Félix Moreno?

Félix Moreno is the current CFO of Xapo. He previously worked in banking and consulting and is a well-know personality in the European Bitcoin scene. 


What do you think is the future potential of cryptocurrencies?

My idea is that cryptocurrencies are going to change payments in the same way e-mail changed communications. No less than that. That is because they are permissionless, like e-mail, as the blockchain protocol can be used by anyone. This for sure will take time. Tools have to be built to make it easy, to make it so simple that in fact your granny can use it.

In times of increased insecurity in the financial markets, why do you think anyone would use a payment network based on a nonphysical and volatile currency?

In fact most people already use nonphysical payment networks. 97% of the money that goes through the European Union is digital. The average customer will not use Bitcoin or any other cryptocurrency until they stop being volatile. The good thing about Bitcoin though, is that you can easily use smart contracts to guarantee the price and stop volatility. Some people are doing that already. The adoption curve will surely go with the volatility. Volatility has already gone down tremendously since the early days and it continues to go down at a steady rate. At 10bn market capitalization it is a lot more stable than it was at 1bn. Furthermore, volatility is a function of volume and stock. The bigger the stock, the more stable something is. That is why the Euro or the Dollar are so stable compared to currencies of smaller economic zones. These currencies are a big stock and there is a relatively small volume exchanging between both. The same thing will be happening with Bitcoin. Bitcoin has the possibility to reach a higher stability in the future than any other currency, as it can be globally used and is not bounded by frontiers.

How do these smart contracts, that you have mentioned, work?

Basically the Bitcoin code allows for certain operations, so called OpCodes. So far there is only a short list of these possible operations, which allow you to set certain conditions to payments. For example, the most useful one right now is called MultiSig. This code allows you to make a payment if two or more people sign. Which means that you can make payments conditional. It is programmable money.

Do you believe that cryptocurrencies will be able to fully replace fiat money?

I think that cryptocurrencies will dominate the Internet before they dominate anything else. But then, as the Internet is becoming a bigger part of our life, they will have a large role to play. This will probably not happen over night and it will need a long time for mass adoption, but exponential movements do happen very slowly at first and very quickly thereafter. We have seen this with social networks. Each doubling took an even shorter amount of time.

Do you think with the evolvement of cryptocurrencies there will be increased intentions from nations to regulate these?

One of the reasons regulators are not doing anything about cryptocurrencies right now is that there aren't yet many users; there is not such a large volume. For them it's not worth it to devote time to that. As the user numbers keep growing, there will surely be intentions to regulate cryptocurrencies. Nevertheless, cryptocurrencies do not care that much about what regulations someone makes up. Just the same as e-mail doesn't care very much. As long as regulators do not regulate the physical aspect, meaning that they stop you from getting an Internet connection, they won't be able to stop it. Additionally, cryptocurrencies can be transferred over many more streams than just the Internet.

Is it complicated for retailers to implement the Bitcoin payment system?

Not at all. It all depends if you want to receive Bitcoins or if you want to receive your local currency. If you want to receive your local currency you need a service provider that will do that for you, such as BitPay. Otherwise it is very easy and can be done through various programs, such as the app Blockchain.

What do you think will be the impact of cryptocurrencies on peoples' everyday life?

Actually there will be only little impact in Europe or the United States, as most people are already familiar with transferring money digitally. Nevertheless, there will be huge impacts in countries such as China, as it comes to regulation, and in Africa, where payment systems are very split between different countries and it's very hard to make international payments. We will see big impacts in remittances; in fact there are several Bitcoin companies that are already focussing on the remittance market. The only problem that remains is that you still have to convert your local currency into Bitcoins, which is a bit expensive right now in many places.

What do you see as the main challenges for a company providing complimentary services for cryptocurrencies, such as Xapo?

A main problem is regulation. We are a regulated company, which slows things down a lot. For example, we have to proceed users' documents or block suspicious accounts. Also regulations sometimes is unclear and it varies in different places. This all costs time and money.

How does Xapo guarantee full security for the Bitcoins stored at your servers?

We provide a product called the Vault, where we safely store our clients' Bitcoins. A vast majority of the Bitcoins are stored offline in cold-storage vaults all around the world. That  prevents them from being hacked.
