How Safe are Bitcoin Paper Wallets?

A bitcoin paper wallet is a public and private key printed on paper or a piece of plastic. It is an offline wallet and is referred to as a type of “cold storage”. This means that it is an extra-secure storage that is not connected to the Internet which can be hacked. Although its security can be debatable.

The piece of paper (or plastic) contains printed private and public keys, usually accompanied by QR code, which also serves as the address. You can simply copy and paste the keys onto a text document and print it out (making sure to delete the document from your PC). You can also use free online services that generate the printable wallet. The key generation is usually done in your browser, so they are not transmitted on the internet. But to be on the safe side, you are advised to clear your browser after printing. Keeping an image of the paper wallet on your computer or phone is a definite no-no.

Some paper wallet services offer a handy design that you can cut, fold and seal, making them a lightweight and relatively secure form of storing your bitcoins offline. You send your bitcoin to the public address displayed on the wallet, and then store the paper in a secure place.

The security of paper wallets stems from the fact that they are absolutely offline, and hackers cannot reach them. But, on the other hand, you need to keep this piece of paper secure to protect your funds.

There is a risk that somebody can find your printout and withdraw your funds without your knowledge. As an extra precaution measure you can fold the printout covering the private key and seal the fold with a tamper evident seal.

Also, you need to bear in mind the physical vulnerability of the material. To protect the paper wallet from water (for example, in case of flooding) you may want to keep the printout in a sealed plastic bag. But there does not seem to be a good protection against fire.

But these risks are not very likely, use common sense to keep your wallets safe the way you would jewels and ordinary cash. In general paper wallets are by far the safest option to store your digital assets.

Whatever your preferred method of storing e-currencies, you can always buy or sell your crypto money choosing the best rates at bestchange.com !

Blockchain and bitcoin based on it, as any new revolutionary technology, have their drawbacks. The mechanism of ‘proof-of-work’ consensus uses enormous volumes of electricity, cryptocurrency is used for speculations and sometimes in illegal activities.

But to say that because of that the technology faces a failure, is the same as saying in 1995 that the Internet will not work because it’s clumsy and unorganized.

Bitcoin has been living for over 10 years now despite numerous predictions of its demise. And it is constantly developing. The first cryptocurrency is no longer a “toy for geeks” as it used to be in 2009. Today Blockstream satellites allow making bitcoin transactions even without Internet.

Blockstream company which deals with bitcoin blockchain pilot projects and New Zealand developer goTenna have united their efforts to improve the project that allows sending and receiving bitcoins without Internet with the help of data translation via satellites using radio frequencies which are supported by goTenna devices.

The users will be able to receive bitcoins via satellite and goTenna Mesh network without direct connection to the Internet. If you do not like the control of the local provider or your connection is down for some reason, for example, because of a natural disaster, you will still be able to make a transaction.

With all the innovative features, this technology is quite easy to use. With an electricity generator, satellite dish, Raspberry Pi, a Wi-Fi point and the necessary software you could make global bitcoin transactions.

At first sight, it sounds rather expensive. But if you divide the expenses among people, for instance, if the whole village chips in for the purchase of the equipment, the costs are not so high. To use this service, you need a small satellite dish that uses USB port to connect to PC or specialized equipment such as Raspberry Pi. To manage connection, you can use free software with open source code, for instance GNU Radio.

And the service itself has demonstrated “excellent” uptime and its network has excess capacity to ensure reliability.

And do you still think that bitcoin does not have any future and nobody uses it?

Blockchain is not a financial pyramid.

To see this, one should understand what a financial pyramid (also called an investment pyramid) is. This is a system for receiving profit via constantly attracting money from new participants. That means the profit of the first participants is paid at the expense of funds of their followers.

It is obvious that if bitcoin does not have any dividend yield, that is, if you do not receive additional funds just because you own cryptocurrency, then bitcoin, as most of other significant cryptocurrencies, cannot be a financial pyramid by definition.

Then why such confusion? Most likely that the reason behind such a poor analogy was the poverty of intellect in most cryptocurrency critics after the events of 2017. They did not even try to learn about the principles and technologies behind cryptocurrencies but started without any reason calling them a financial pyramid. Partially they can be understood, because the previously unknown project that made it possible for people to increase their capital several times over a few months sounds very suspicious.

But what happened is that people earned profit due to the increase in the price of the active, and not because of the means of new users. Yes, to some extend it was the dramatic increase of popularity that brought about price increase, but these concepts should not be confused. Situations when demand starts to dramatically exceed supply are always accompanied by similar price increase. These can be company shares, investment fund units or even salt that can rise in price against the backdrop of false rumors. Price increase due to the growth of demand is a typical market situation, and not a disguised financial pyramid.

That being said, blockchain-based pyramids can sometimes be found, for instance, PonziCoin and Bitconnet. But these are particular cases of the misuse of the technology in creating a financial pyramid, and not vice versa.

It should be noted that there are financial pyramids that are disguised as cryptocurrency projects, only exacerbating the suspicion of inexperienced crowd. For example, they can promise profit thanks to a “unique trading robot” that multiplies your investments, or something of this kind. Of course, they have nothing to do with cryptocurrencies, and the illusion of work is maintained at expense of new client’s investments.

We hope that we have made our point clear. And what other unreasonable definitions of bitcoin have you come across? We would be happy to discuss it with you in our next articles.

Cryptocurrencies were originally envisioned as a decentralized payment means, independent of fiat money rates and not tied to traditional valuable assets.

This peculiarity adds cryptocurrencies a characteristic feature — high volatility of the rate. Many folks gain thanks to this feature, but the possibility that the rate can dramatically drop or leap hinders the usage of cryptocurrency as a full-fledge payment means.

In order to regulate the rate, it was decided to tie up cryptocurrencies to stable assets that have long been established in the economy. Thus, they began to tie up the value of cryptocurrency to fiat money, gold and oil. Digital currencies can be tied up to any valuable asset or commodity which can make their value more stable.

Cryptocurrencies pegged to physical assets have a lower rate volatility and became known as stablecoins. Stablecoins are a compromise between fiat money and cryptocurrencies. Most often, the value of a stablecoin is pegged to fiat money. The value of these coins is equal to that of fiat currency and represents a sort of a promissory note. Every coin is leveraged to one unit of fiat money, for instance, dollar, which acts as a guarantee and provides for the value of the currency.

The most popular stablecoins are:

Tether (USDT) * USD Coin (USDC) * TrueUSD (TUSD) * Paxos Standard Token (PAX) * Dai (DAI)

And what stablecoins do you use?

Did you know that in its modern form, credit card appeared back in 1949? Originally nobody took them seriously, but within the next few years they literally conquered the whole world.

The first universal credit card, which could be used at a variety of establishments, was introduced by the Diners’ Club, Inc., in 1950. Another major card of this type, known as a travel and entertainment card, was established by the American Express Company in 1958.

Today billions of people around the world use bank cards. The share of cashless payments is gradually growing, and they become a usual and more convenient method of payment.

According to statistics, for the year 2015, debit card usage accounted for 69.5 billion in payments, dwarfing all other forms of non-cash payments including credit cards (33.8 billion) and checks (17.3 billion). One new debit card is issued in the U.S. every five seconds. There were 471 million Visa debit cards in the U.S. and 1.09 billion in the rest of the world at the end of March 2015.

How many bank cards do you have? How often do you use cash?

The Amsterdam Stock Exchange is considered the oldest in the world. It was established in 1602 by the Dutch East India Company, which issued the first shares on the Amsterdam Stock Exchange. It was the first company to issue stocks and bonds and the first to formally begin trading in securities.

In the 1600's, the Dutch, French and British governments all gave charters to companies with East India in their names. At the peak of imperialism, it seemed like everyone had a share in the profits from the East Indian and Asian campaigns except the people living there. Sea trips that brought back commodities from the East were very risky - besides pirates, there were risks of weather and losing navigation.

To minimize the risk of a lost ship ruining their profits, ship owners had long been using the help of investors who would finance the trip - outfitting the ship and crew in return for a percentage of the profits if the voyage turned out a success. These early limited liability companies often lasted for only a single voyage. They were then dissolved, and a new one was created for the next trip. Investors lessened their risk by investing in several different ventures at the same time, thereby playing the odds against all of them ending in disaster.

When the East India companies formed, they changed the way business was done. These companies issued stock that would pay dividends on all the proceeds from all the voyages the companies undertook, rather than going voyage by voyage. These were the first modern joint stock companies. This allowed the companies to demand more for their shares and build larger fleets. The size of the companies, combined with royal charters forbidding competition, meant huge profits for investors.

Is a quantum computer dangerous for Bitcoin?

Many researches say that in less than 10 years сomputing machines using quantum principles will threaten blockchain technology which is a basis for cryptocurrencies.

Bitcoin and similar systems’ defense algorithm is based on a principle of asymmetric encryption with and open and private keys. Transaction is signed by a private key, and its truth is checked with a help of an open key.

Despite the fact that Bitcoin blockchain uses asymmetric encryption, the users don’t have to worry for the safety of their coins. The open key is not stored openly. Thus, the addresses for coins transferring are not open keys, but just the results of usage of hash-function SHA-256. The hashing function performs one-sided transformation and that’s why it’s stable against quantum computer attacks.

The public key is rendered to the network in the open way just until it receives a confirmation. If an attacker receives an open key during transaction, he will have around 10 minutes to get the private key with the help of a quantum computer and try to make his own transaction from the same address but specifying a larger commission.

By the way, bitcoin mining is also relevantly safe, as the equipment for mining cryptocurrencies in the near future will be more powerful that quantum computers.

It is worth to note, that quantum calculations threaten absolutely all systems of computer security which care based on cryptography with an open key, and not only blockchain. Internet connections to render your password in Internet banking uses a similar encryption technology, same as communication in chatrooms, social networks and lots of other routine actions.

All security systems, including blockchain systems, need to take into account postquantum encryption to ensure data safety. But the most simple and effective way can be changing traditional systems by such blockchain which implements quantum-resistant cryptography.

There are several different ways of encryption with open key resistant to quantum calculations: bases on matrix, on code, multidimensional quadratic functions, and hashing function. But let us not digress into detail math stories.

The main point is that if there is a serious threat to blockchain posed by quantum computer, developers can improve the protection. Moreover, successful research and developments in this regards are being done not for the first year.

What do you think, who will be the first in this race – bitcoin developers or quantum computer developers?

Sometimes it is necessary to confirm that you are the owner of this or that address. This may be required when, for instance, the seller wants a confirmation of your solvency, when recovering a hacked or lost account, or to prove that it was you who made a transfer and not somebody else.

Only owning a private key can prove your ownership of a bitcoin-address, but at the same time you cannot give away your private key: anybody with an access to it can spend your funds.

To solve this contradiction, a special function was developed – “signing a message”. When you sign a message, you can prove that you own a certain address and manage its funds. At the same time, secret information is not revealed, and no risk is posed for the funds at this address.

Creating a signature for any message is possible with lots of bitcoin-wallets. You will need to specify the address you need to confirm, and a message. The text can be of any nature, but it’s preferable it would tell something to the recipient. We advise you to always put the date and the reason of the message. If you sign any message without the specifics, somebody else might use it and pretend to be the owner of your address.

After signing the message, you can give the message with your signature to the other participant which will prove your ownership of the address. To check the signed message, it is possible to use a wallet or other resources.

Have you ever used this function? Have you heard about signing the messages for cryptocurrency wallets?

What are the Advantages of Cryptocurrency?

Over the last couple of years, cryptocurrencies gain more and more popularity. Let’s touch upon some of their main advantages in comparison to fiat money.

1. It is decentralized and does not rely on banks or governments. Transactions can take place in different parts of the world and take seconds, without the need to pay hefty charges to banks.

2. Because cryptocurrency is decentralized, it’s immune to deflation or inflation that can happen as a result of the choices of a central government.

3. Anonymity is one of the most important perks of cryptocurreny. You do not need to reveal your identity.

4. Anybody can make money through the process of mining. All what’s needed is access to a computer and the internet.

5. Because the cryptocurrency market is highly volatile it can be a high reward (but at the same time, high risk) investment.

6. Cryptocurrency is not subject to inflation. With coins like bitcoin there is a set amount that will ever be created.

7. And last but not least, since cryptocurrency exists in digital form, millions of trees can be saved by not using paper currencies. It can contribute to our environmental well-being.

You can purchase or sell cryptocurrency at BestChange – we guarantee the smoothest exchanging experience, saving your time and money!
