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?June 25, 2019 at 9:22 am #21539
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?July 2, 2019 at 3:45 am #23784
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.July 3, 2019 at 6:22 am #24967
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?July 17, 2019 at 6:35 am #36264
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?July 30, 2019 at 8:33 am #36752
Exactly 63 years ago on July, 30, 1956, the slogan “In God We Trust” appeared on American dollars.
Moreover, the phrase is an official motto of the USA.
The first time the motto was used in 1864 when minting 2 cent coins, but it was adopted on the national level in 1956.
Sometimes the phrase is jokingly extended to “In God We Trust, All Others Pay Cash” which shows economic attitude of Americans, and shopkeepers would use it to discourage credit.August 28, 2019 at 2:36 am #39349

ℹ️The cost of bitcoin transaction fell by almost 90%
BTC trades almost reached the level of the end of 2017. This is the period when the main cryptocurrency began its famous rally, the peak of which was the increase in the coin rate up to $ 20,000. According to the information of Bitinfocharts service, since that moment the cost for transactions has dropped by almost 88%. In December 2017 commission was around $10-30, and now it has fell down to $0,58 on average. It can be due to considerable popularity of processing operations of BTC transactions at the end of 2017 in comparison with today. Then up to 400 000 operations went through the network daily, when now this figure has dropped to 300 – 350 000 transactions. Another factor influencing the commission cost is the growing popularity of SegWit protocol, the share of usage of which has recently exceeded 60 per cent.
ℹ️Transparent Volume experts: Only 17% of bitcoin transactions do not raise suspicion
According to the new service Transparent Volume of the Nomics cryptocompany, the majority of transactions with the main cryptocoin are suspicious. The experts say that only 17% of BTC operations can be considered genuine. Around 35% of transactions are evaluated within the range from “satisfactory” to “bad”. The total amount of such operations today has reached $3,99 billion.
Transparent Volume is created to monitor the circulation of digital asses between different platforms. It works in real time. Nomics believes that usage of Transparent Volume will help users obtain full and objective information about current trade volumes. The service positions itself as a platform whose work is associated with lesser risk of recording information about fictitious transactions and other misleading facts.September 9, 2019 at 7:14 am #39666
There are prospects: forecasts of digital currency market participants
This week was full of various events for both participants of the cryptocurrency industry as well observers. Here are some expert comments on the current development of the digital asset market.
On Monday Yves Mersch, Member of the Executive Board of the European Central Bank (ECB) criticized Facebook’s Libra.”Libra could reduce the ECB’s control over the euro, impair the monetary policy transmission mechanism by affecting the liquidity position of euro area banks, and undermine the single currency’s international role” . The official has also noted that Facebook’s cryptocoin will in fact be accountable to shareholders, raising trust issues, as it will not be backed by a central bank. Mersch called on regulators to take tight control over Facebook’s projects, and for users not to trust the tempting but questionable promises from the representatives of the American company.
Meanwhile, Jack Dorsey, the head of Square payment start-up and Twitter co-founder, continues to insist that cryprtocurrencies will continue to spread. The businessman believes in bitcoin, but he thinks that it is still too early to call it currency. In one of his latest interviews Dorsey notes, that bitcoin’s rises and falls in prices are more characteristic of a investment asset, such as gold. He hopes that as soon as the cryptocurrency becomes the currency of the Internet, his own start-up will pay more attention to services that create added value, rather than those that are engaged in money transfer
Mark Mobius, an investor in developing markets and Mobius Capital Partners founder said that gold-backed cryptocurrency can be an interesting phenomenon. The investor emphasized that there is a whole generation of people who have faith in the internet, and they have faith in cryptocurrencies.
“People believe in dollar because they have faith that with dollars in their hands they can buy something. Crypto enables people to buy something merely because they believe it has value”, Mobius said.
In the beginning of the week trader Peter Brandt tweeted that bitcoin has entered the fourth cycle of the parabolic uptrend that could lead it significantly past its all-time high price. The analyst is confident that the price of Bitcoin will reach one hundred thousand dollars in the long run. And although this bold prognosis does not yet have lots of supporters, one can’t ignore the fact that the price of the main cryptocoin is showing steady growth since Monday.
According to Coinmarketcap, by September,6, bitcoin rose in price up to $10 875, starting from the mark of $9 623 on the night of September,2.September 14, 2019 at 2:06 pm #41124

The market of popular crypto currencies is still in the “red zone”
During the last day the price of bitcoin was gradually growing. However, the crypto coin, as well as the other top-10 tokens, has not yet left the “red zone” of the market. According to Coinmarketcap, at 15:00 CET, the first crypto coin’s price was $9,690.
Market players have different opinions in this regard. Some insist that they hope for the prospect of BTC growth. Others say that there are no drivers for growing in price yet, and the price fluctuations are strictly speculative in nature.
During the last 24 hours, Ethereum dropped more than by 6%, having reached $197. Litecoin has demonstrated the most dramatic drop (-9.23%), having fallen down to $66.
Opinion: BTC is now more stable than a year ago
Alex Krüger, the famous cryptocurrency trader, expressed an opinion that currently the position of the first cryptocurrency is much more stable than it was in 2018. Then, the average trading BTC rate was at the level of $6,400, and this year the crypto coin has managed to get over the $10,000 mark.
The crypto enthusiast believes that the BTC rate growth signals the average increase of crypto coin’s popularity. The gradual adoption of bitcoin is also indicated by the fact that 25 thousand retailers in France, for instance, the Sephora network, plan to accept the first cryptocurrency. It is scheduled to happen already in the beginning of the following year.
Nigerian government official paid $15K ransom in Bitcoin
In a publication for Daily Trust, Nigerian government official Dr. Umar Ardo said the criminals made him pay a $15,000 ransom in bitcoin to release his kidnapped daughter.
Last week, Dr. Ardo’s daughter Amado was kidnapped at a gunpoint around a shopping center. What strikes about this incident is that it is for the first time in history that criminals demand payment in cryptocurrency.
Why in bitcoin? Investigators believe the criminals requested the ransom to be paid in bitcoin to remain anonymous and escape penalty, since blockchain transactions are completely anonymous.
Sadly, incidents like these cast a shadow at the refutation of cryptocurrencies. Despite the indisputable advantages of blockchain technology, many leaders have voiced concern regarding anonymity connected with that.ndustry innovations will push the payment systems to search for original ways for development. Only this way they will be able to meet competition and tap into new markets.
