Launched in 2008 by the famous Satoshi Nakamoto, Bitcoin is a form of digital currency. It is the best known and most widely used form of cryptography today. Even though it is a digital currency, it allows you to carry out various transactions. Here are some ideas on how to use your Bitcoin portfolio safely.

Paying for various purchases of products and services daily

Contrary to popular belief, Bitcoin is not only usable online. You can pay physical merchants for your everyday purchases. Not all merchants accept it yet, but the number is growing every day. There are even bars, restaurants, and department stores that allow this alternative means of payment.

Nevertheless, Bitcoin will be more useful to you at the moment for paying for services on the Internet. Do you want to create your website? Optimize its referencing? Use a VPN? Buy digital products, such as software and video games? You can do it without any problem. More and more sites offer you the possibility to pay for your purchases in Bitcoins.

Entertain and have fun online

The gaming industry is one of the few sectors that never experience the crisis. With the advent of the digital age and the democratization of the Internet, you can play a large number of games online while staying at home. Online casinos can accept Bitcoin and other crypto money and are becoming more and more numerous. For a good reason, digital currencies are ideal for making dematerialized payments on the web.

Exchanging them in traditional currency

You have earned Bitcoins in your virtual wallet and would like to exchange them into fiat currencies? It is entirely possible. Some cryptocurrency platforms offer you this type of service. Some even offer you a prepaid debit card that allows you to convert your Bitcoins into dollars or euros automatically. If you want, you can also use your card directly to pay for your online purchases, for example, on Amazon.

Investing in real estate and building assets

A few years ago, Bitcoin was still a vague computer concept. Today, it is now accepted as a simple, fast, and secure means of payment. By fulfilling all the basic functions of conventional currency, this cryptocurrency can be used for investments. Do you intend to invest in real estate? You can finance your project with Bitcoins, whether it is a building construction to make it your residence or acquisition to be an owner-lessor. In the first case, you build up your real estate assets. In the second case, you enjoy the benefits of the rental income.

Blockchain is the basis of all cryptocurrency, and there is a lot of information about how this works. If you are new to cryptocurrency, there are certain facts that you should know about the blockchain and how it works. This will provide you with a better understanding of cryptocurrency and how they are created and managed.

Blockchain Is A Distributed Ledger

When you look at how blockchain works in simple terms, it is a distributed ledger. It means that it is a real-time ledger of all the financial transactions which have been completed with a cryptocurrency. There is no one person in charge of maintaining or changing the ledger as this is done as and when the transactions occur.

The blockchain of a currency will work on a peer to peer network of computers which are called nodes. Each node will be in charge of checking parts of the ledger, but the entire ledger is entirely decentralized.

Blockchain Records Cannot Be Altered.

When a transaction is recorded in the distributed ledger, it cannot be altered. This is due to the fact that when the ledger is updated, all accounts will be updated and there is no way to update all copies of the ledger on all the nodes. When a transaction is completed on the blockchain, it will be grouped in a block. Each of these blocks will be attached to the blocks that came before, so changing an older block will need newer blocks to be changed as well.

This method of work will result in a ledger record that is chronological and cannot be tampered with. Each new block added to the chain will receive a reference to the hash of the previous block which secures the data further.

There Are Many Uses For Blockchain Technology

When people think about blockchain, they will think about cryptocurrency. However, there are many other ways that this technology can be used and there are a lot of companies that are looking into this. These companies have seen the potential of blockchain for other uses such as secure company data and the verification of information.

There are also many people who are under the impression that there is only one blockchain which is used for everything. It is incorrect as blockchain is a form of technology can be created and used by anyone who would like to. If you look only at the cryptocurrency, there are several different coins that you can purchase, and each of them will have their blockchain. The blockchain which is used for Bitcoin will be different from the one that is used for Ethereum because they are different coins and need different ledgers.

There are a lot of facts that you need to know about blockchain technology. It is essential to understand how the blockchain works and the fact that anyone will be able to use it. The security of the transaction records is one of the reasons why more and more people are looking to use blockchain for new purposes.

The explosion of Bitcoin in 2017 revealed to the general public a virtual world that was rather discreet since 2010. With over 1800 new currencies of the genre, boasted by the now famous blockchain technology, the complexity of this industry greatly increased over the past 5 years in an industry that is now trying to set the tone for future financial freedom.

This is the story of cryptocurrency.

It all started in 1998, Wei Dai released a “b-money” device, an anonymous electronic treasury system, but it was the Bitcoin, created in 2009 by a developer whose pseudonym is Satoshi Nakamoto, that launched the cryptomarket as we now know it. Later, other major cryptocurrencies appeared, like Litecoin, Peercoin and Namecoin, all with different properties.

Many others have been developed but have not been very successful, mainly because of their lack of innovation.

During the first years of its existence, cryptocurrencies attracted the general public little by little, especially through the interest of the media, and since 2011 we have been able to notice an increasing success of the subject, notably during the sudden rise of the Bitcoin price in April 2013 (it is at this time that consumers really knew this currency and its strong potential).

From 2014, a second generation of digital currencies has made its entry on the market, with Monero, Ethereum (derived from Bitcoin and referent of this second generation) and Nxt for example, and their new features such as stealth addresses, intelligent contracts, or lateral blockchain chains, among others.

Robocoin’s founder launched the first Bitcoin vending machine in the United States in early 2014.

The kiosk is located in Austin, Texas and is similar to bank machines, but is equipped with scanners to read ID cards to confirm the identity of users. Finally, the market capitalization of cryptomonnaie should reach 1 000 billion dollars in 2018.

Major challenge for institutional money

Today, the cryptocurrency market represents a major challenge for central banks and the global economy because the rules of the game in this environment are quite different from those of traditional currencies, and the growing popularity of cryptomonets could cause consumers to lose confidence in fiduciary currencies, which is essential: a currency is valid when consumers believe in it, otherwise it can collapse.

That’s why several countries have studied the question to create state cryptocurrencies. In January 2018, the Bank of England announced its intention to create a cryptocurrency indexed to the British currency. In Canada and Singapore, institutions are also considering developing cryptocurrency payment systems. This year, the Marshall Islands became the first country in the world to launch a legal cryptocurrency, and the Venezuelan president created a cryptocurrency, petro, anchored on the price of a barrel of oil, in order to circumvent the American sanctions that affect the country.

In any case, the cryptocurrencies and his blockchain account book seem to have a bright future, and since everyone can try their luck, why shouldn’t the next person to consult the blockchain be you?

In less than a year, the Bitcoin soared to over $19,000 before undergoing a severe correction. An almost unprecedented performance in the history of the markets. Financial revolution or a simple bubble? Our analysis.

It’s the star of the moment. On the markets, one speaks “almost” only of Bitcoin, so much the cryptocurrency shows stratospheric performances.

Despite these fluctuations, the number of investors has increased considerably, to over 50 million users, while investment banks and funds have positioned themselves in the niche. Even economists have taken up the subject. But where does this cryptocurrency that unleashes passions come from, how does it work, is it secure, how far will it climb?

Bitcoin, what is it?

Bitcoin is not a stumbling block of change. It is a cryptocurrency, i.e., a “currency” that takes the form of an encrypted computer program.

This currency was launched in 2009 by a group of unknown hackers, hidden behind the pseudo “Satoshi Nakamoto.” The computer program is equivalent to the DNA of Bitcoin, which defines its technical characteristics and operating mode.

If not controlled and guaranteed by a central bank, Bitcoin is protected by blockchain technology. The “blockchain” is a kind of giant numerical account book that acts as a ledger. It lists and secures all operations performed with bitcoins.

Who uses Bitcoin?

There are mainly two types of investors. Individuals and institutions. The number of private users is estimated at 30 million, almost half of them in the United States. For most of them, it is primarily a speculative investment, to try to take advantage of the bullish wave.

On the other side, there are institutional investors, investment funds in particular, who are more discreet but are very present. These players want to position themselves on a new financial asset. On December 10, the Chicago Stock Exchange launched a futures contract on Bitcoin, while the French fund Tobam decided to offer its clients to invest in cryptocurrency.

Is it secure?

Investors and… hackers are coveting the explosion in the value of Bitcoin. For several months, attacks have multiplied, causing the closure of dozens of cryptomarket “exchanges,” platforms on which investors buy and sell Bitcoin.

A few days ago, the Youbit platform, the fourth largest operator in South Korea, closed its doors after being the victim of a new computer attack, attributed to North Korean hackers. Nor is the sector more exposed than others, such as industry or finance, which are also under attack from IT, even if there are calls for the crypto exchanges to be grouped in order to pool their costs and strengthen their protection system.

How high can it go?

That is the question that is agitating the markets. In December, Bitcoin had sessions with increases of over 30%. Since the beginning of the year, the Bitcoin price has increased more than 15-fold, from $900 to over $17,000, with a peak of $18,000.

Few financial assets have experienced such growth. Only a few stock market values and “penny stocks,” these values whose share is only worth a few cents, posted comparable increases.

Potentially, Bitcoin has no limits as long as demand increases. It could continue to climb in the coming weeks, especially if the futures contracts launched by the Chicago Stock Exchange give credibility to its financial normalization.

There is no universal Bitcoin wallet. These wallets come in all kinds of forms and functions.

What is a Bitcoin wallet?

A Bitcoin wallet is the first thing you need to be able to use bitcoins.

Why?

Without a wallet, you cannot receive, keep and spend your bitcoins.

Try to imagine such a wallet as your interface with the Bitcoin network – a bit like your online bank account is an interface to the conventional monetary system.

Bitcoin wallets contain private keys, some secret codes that allow you to spend your bitcoins.

These are not the bitcoins that need to be stored and secured, but rather the private keys that give access to them.

In brief:

A Bitcoin wallet is an app, website or device that manages your private keys.

Types of Bitcoin wallets

Hardware Wallets

A hardware wallet is a physical, electronic device designed for the sole purpose of securing bitcoins.

The big difference with solutions is that the hardware devices must be connected to your computer, smartphone or tablet before you can spend bitcoins.

The three most popular hardware wallets are:

• Ledger Nano S
• KeepKey
• Trezor

Hardware wallets are one of the best choices when you take security seriously, but still, want a convenient and reliable bitcoin storage solution.

Hardware wallets keep private keys away from devices connected to the Internet (and therefore vulnerable).

Your private keys are stored in the wallet hardware, i. e. in a secure offline environment offering complete protection, even when the computer to which it connects is infected.

Since bitcoins are a digital currency, cybercriminals could theoretically attack your computer’s “software wallets” and steal them by gaining access to your private key.

Which wallet suits you best?

To invest? To save money? In this case, a hardware wallet will allow you to keep your bitcoins safe.

If not, a software wallet can also send and receive bitcoins.

Each wallet has its advantages and disadvantages, and each wallet exists to solve different problems.

Some wallets focus on security, while others focus on confidentiality.

Your needs will determine the type of wallet you use because there is no such thing as the “best Bitcoin wallet.”

Mastercard offers for the first time the possibility to send money via a blockchain instead of using a credit card.

After developing its version of blockchain technology over the past two years, Mastercard announced on Friday that it is now opening up blockchain technology to individual banks and merchants as a potentially more efficient alternative to paying for goods and services.

A sign that the widespread adoption of crypto technology is on the rise, Mastercard is the second Fortune 500 company this week to start making payments easier with it. On Monday, IBM revealed that it had also begun making payments on its proprietary blockchain between banks in the South Pacific.

Like IBM, Mastercard also targets business-to-business payments as the primary objective of its blockchain, which can only be used by invitation. Mastercard, however, differs from the technology giant importantly: while IBM’s blockchain transmits only money in the form of Lumens, a virtual currency created by the non-profit company Stellar, the blockchain Mastercard operates independently of a cryptographic currency and instead accepts payments in traditional local currency.

Not a real currency?

On the other hand, according to Pinkham, Mastercard has an advantage that the Bitcoin does not have: a settlement network that includes 22,000 banks and financial institutions around the world.

After all, Pinkham adds, companies still rely primarily on government-issued money for business, which makes it impractical to convert cash into cryptographic money, or vice versa, for every payment on a blockchain. Even in the bitcoin system, there needs to be a trading platform that allows Bitcoin to be exchanged for the euro, which creates complications,” Pinkham explains.

Mastercard hopes to offer the benefits of this technology, including a safer and more transparent way to make and track payments within the existing financial system, without the drawbacks of digital money. What Mastercard brings to the table here is a unique combination of this blockchain capability and Mastercard’s settlement network,” Pinkham explains. (The competitor credit card provider Visa, for its part, has partnered with startup Chain to develop its own similar business-to-business payment system.

Some companies have already signed up to use Mastercard’s blockchain, Pinkham said, although he refused to name them. In addition to payments, Mastercard envisages that businesses could use this blockchain to track the movement of pharmaceuticals and luxury goods such as handbags and diamonds, thereby reducing fraud by providing “proofs of origin.”
