1. What is mining?

Today, even those who are not really familiar with cryptocurrencies have definitely heard something about mining. However, it is not always clear what it actually is.

Mining is a computing operation. In fact, this is a kind of an attempt to solve a complex mathematical problem. The particular “X” that must be found as the result of the calculations is called a hash. If it is successfully found a new block is generated in the cryptocurrency blockchain. A block is a structural unit where the information about cryptocurrency transactions is recorded. It is sometimes not that easy to get all those terms, so let`s take a look at a rather simple example: a block is a kind of a banknote. Any banknote is a legal tender only if it looks in a certain way. It has a special design, watermarks, other security features, particular density, etc. Each banknote must meet certain specified parameters, otherwise, you will not manage to buy something for it and it will be just a piece of paper. The same thing with cryptocurrencies! Transactions are confirmed by being recorded into the blocks, and the blocks must be valid, must have a particular form. To meet this form, to generate a valid block, a hash with required parameters should be found as the result of computing operations. And that is exactly what miners are responsible for!

2. How is Bitcoin mined?

Bitcoin is a Proof-of-Work algorithm-based digital currency, that is why BTC is mineable. Proof of work actually means that transactions are confirmed, and the blocks are generated only if a certain work is done – new coins are issued only when one has managed to find the hash and create a new valid block. Every new block is generated approximately once every ten minutes. The Bitcoin code is written in such a way that, depending on the computing power in the network, the difficulty of the hash varies. In other words, the more powerful the miners are, the more difficult it is for them to find the hash. That is how the system maintains the balance between the available computing power and the complexity of the calculations. It does not matter whether only several personal computers are engaged in Bitcoin mining (as it was in 2009) or huge industrial mining farms (as it is happening today) – it will always take approximately ten minutes to generate every new block.

So, when miners do their calculations successfully and manage to find the hash, they are rewarded. This reward used to be as huge as 50 BTC. However, back then the number of coins was not actually a significant fortune. According to the Bitcoin code, this reward decreases by half every 210 thousand blocks. Since each block of Bitcoin is generated in about 10 minutes, it takes about four years to get 210 thousand blocks. So, every four years the reward is reduced by half. In 2012, there was the first reduction from 50 BTC to 25. The next reduction took place in 2016. Today miners get 12.5 Bitcoins for each generated block.

3. How many Bitcoins can be mined and what’s the time period for that?

It is only possible to mine a total of 21 million BTC. This maximum amount of cryptocurrency is provided by its programming code. First of all, this limitation is designed to prevent inflation and preserve the value of Bitcoin. Actually, those things are usually valuable, that have a limited supply, and if Bitcoin had an unlimited emission, like Ethereum and some other virtual currencies, it would have been potentially subject to inflation. As of mid-October 2018, according to coinmarketcap, the number of BTC coins in circulation reached 17,332,325, which means that only a bit more than 3.5 million coins remain to be mined. It would seem not a big deal – almost all Bitcoins have already been mined! But truth is, it will take more than a century to mine the remaining coins!

So, let’s see how long will it take for miners to get all Bitcoins. To calculate this, we should make several mathematical operations. Of course, these operations are not as complicated as those required to find Bitcoin hash. The computing power of your calculator will be enough! So that is what we have:

The reward is reduced by half every 210 thousand blocks (approximately once every four years). Accordingly, the number of coins issued will decrease every four years. So, 10.5 million BTC was issued during the first “four-year cycle”, when the reward for each block was 50 BTC. Then the number of coins is reduced by half with each cycle. According to this formula, the very last BTC will be mined about the year 2140! Interestingly, in the first seven “four-year cycles”, miners will extract 99% of the coins, and it will take more than a century to get the remaining 1%.

4. Types of Bitcoin mining

About ten years ago, when the first peer-to-peer decentralized payment system with a cryptographically protected digital cash (yep, it’s all about Bitcoin) was launched, there was only one, or perhaps several miners, in the network. Probably it was an ordinary PC or laptop owned by Satoshi Nakamoto – the mysterious Bitcoin developer – and maybe some other PCs owned by those involved in the development of Bitcoin. So initially users were able to mine Bitcoin using their own devices. The computing power of their processors was enough to perform necessary calculations and find Bitcoin hash. This type of mining was called CPU-mining. However, with the growing popularity of Bitcoin, more and more people joined the system, the load and difficulty increased, and eventually, it became clear that even the most powerful PC had not enough power to mine Bitcoin effectively. A casual user with his laptop was left behind. And the reason is that a probability of getting a reward is equal to the ratio of your individual computing power to the power of the entire network. So a new solution was found – users started mining Bitcoins using the computing power of video cards. That new type of mining was called GPU-mining. Several video cards were connected to a computer and the entire powerful device used special software to mine BTC. Today, a number of cryptocurrencies can still be mined using processors or video cards, but this is not working out with Bitcoin. To be able to find Bitcoin has users should make really complex calculations and special high-performance devices are required. These are ASIC-miners – a special equipment with high computing power and price.

Today users who have special equipment for BTC mining combine their computing power in special mining pools. Pools are groups of miners who use their computing power together and jointly perform the operations necessary to obtain Bitcoin hash. The probability of getting a reward is much higher than if users mine the cryptocurrency solely. This reward is then distributed in proportion to the computing power “invested” by each individual miner.

Moreover, cloud mining is also relatively popular. This, in fact, means that a user simply rents computing power from owners of large mining farms, who are often the manufacturers of mining equipment. Despite the fact that today this type of mining is gradually becoming less attractive, it still has its advantages – users do not need to buy equipment, place it, set up, maintain its operation, update hardware, pay for electricity, etc.

5. Prospects of Bitcoin mining

Many believe that the mining era is almost over and there are some reasons for this. After all, as we have already figured out, even the cryptocurrency code itself provides a reduction of the reward. If Bitcoin rate does not increase significantly, nobody will be interested in running expensive mining equipment and earning a couple of thousand satoshi (1 satoshi is 0.00000001 BTC).

Today mining is a fairly centralized industry with and it is rather difficult for beginners to join it. Especially for those who do not have a lot of money. Even owners of huge industrial mining farms experience some problems. For example, some of them realize that the equipment they used in 2017 cannot provide the same profitability in 2018. Today BTC mining is largely controlled by mining pools one hand and owners of huge industrial mining farms on the other and this tendency for mining to become more centralized is likely here to stay.

6. Conclusion

So, Bitcoin mining is not a “gold rush” anymore. The increased difficulty made it way more centralized and way less available for casual users. Today, mining still provides big profit for those who own huge mining farms or at least some high-performance equipment. The Bitcoin rate is far from the historical maximum, but nevertheless, it remains quite significant, and most importantly, according to many experts, has prospects for an even greater increase. However, today it is practically impossible to make money on mining without big preliminary investments. Mining prospects depend on the rate of cryptocurrency, and on the other hand, are also predetermined by the Bitcoin programming code itself. However, this predetermination can be defined differently. Yes, the reward is reduced every four years, so mining can become less appealing in the future. But this reduction can be compensated if Bitcoin price increases. Anyway, today many crypto enthusiasts consider other mining options. Sometimes it is easier to mine other coins, and then, if desired, exchange them for Bitcoin. One thing is clear – the mining industry has been changing, and the time will tell,  what will happen to it in the medium term.

BitPay Transactions Surpasses $1B in 2018, B2B Payments Records 225% Increase

BitPay is a US-based bitcoin payment provider which has recently announced its financial results of the past year. The company has processed over $1 billion in transactions alone. Moreover, its B2B payments record 225% increase in compare to 2017.

The main reason of such a lift-off is that Bitpay added a lot of new clients, like Dish Networks, HackerOne, and the State of Ohio, as well as many other law firms, data center providers, and IT vendors.

The CEO of BitPay, Stephen Pair, commented on this development:

“BitPay’s B2B business continues to grow rapidly as our solution is cheaper and quicker than a bank wire from most regions of the world. To process over a $1 Billion for the second year in a row despite Bitcoin’s large price drop shows that Bitcoin is being used to solve real pain points around the world.”

BitPay mostly supports Bitcoin transactions, however, it also supports payments with Bitcoin Cash, Gemini, and Paxos. During that year a lot of companies had to lay off their employees due to the market situation, yet, Bitpay conversely increased its manpower by 78 percent in the past year.

In addition, BitPay is attractive to the investors, in 2018, it raised $40 million in Series B funding round taking the total raised capital to $70 million.

New Useful Gadget or Promotional Trick: What Is the WT2 Plus Earphone Translator?

A language barrier is the main cause of disagreements and the reason why people of different nationalities cannot fully communicate. But, besides, a language barrier complicates the lives of many travel lovers. Soon this problem will fall into oblivion, as its solution was suggested by Timekettle company in the form of a new gadget WT2 Plus. Now this device is presented at the International Consumer Electronics Show CES-2019 in Las Vegas.

What is WT2 Plus?

This is a wireless earphone translator, which will become an integral gadget when traveling to foreign countries. The novelty caused a huge interest and made many people wonder: “What is the price of WT2 Plus?”. You can breathe a sigh of relief, because the answer is already there! The cost of WT2 Plus is $ 219.

Source: http://www.timekettle.co/

How does WT2 Plus work?

The earphones support Android and iOS operating platforms. They connect with a mobile device via Bluetooth using the application that allows users to set a language. At the moment, the application supports 20 languages, but in the near future the developers will add another 15.

The feature of the application for WT2 Plus is recognition of various accents. For example, the application supports 5 accents of English, including Australian English.

Direct use of portable earphones occurs as follows: in order both interlocutors can talk and hear each other, each puts one earphone from the kit on. When talking, the earphones transmit the sound to the smartphone for translation and transferring the translation back to the earphones. The delay in processing and transferring sound takes only 3-5 seconds, depending on a sentence size.

Even though the manufacturer emphasized the possibility of real-time translation as its main advantage, in fact the device is capable of translating only short phrases, the duration of which do not exceed 15 seconds. For example, the gadget can not be used for continuous translation of a film in a foreign language.

Regardless of the headphones’ being wireless, they will not catch environing phrases and translate them due to the built-in “Touch” mode, which allows you to use WT2 Plus in crowded places.

The earphones themselves are stored in a pocket-case that resembles Apple’s AirPods case. The earphones are charged from the case. Each earphone has a 110 mA battery, and the case battery capacity is 320 mA. Full charge of the earphones takes 90 minutes. The case works for two weeks without recharging, it is enough for two recharges of each earphone.

The manufacturer plans to increase the accuracy of the WT2 Plus translation to 95%. The translation requires access to the Internet, since it is carried out through Google and Microsoft cloud servers.

How to Get Bitcoin And How Profitable is Mining in 2019

Appearance of Bitcoin has marked the beginning of a new era in development and dissemination of money. 2018 became a crucial point for cryptocurrencies. In this article we will talk more about Bitcoin mining, find out what is needed and how to earn from it.

1. What is Bitcoin mining?

BTC mining is carried out with the help of specialized computer equipment, so-called Bitcoin farms. In order to open a new block, the miners resolve complex mathematical problems, for which the network rewards them with X number of coins.

Bitcoin algorithm is designed in such way, that every 210 thousand blocks the reward decreases exactly by twice. At the very beginning, miners received 50 coins for each new block, then this number was reduced to 25, and now this value is 12.5 BTC.

2. What are the ways to get Bitcoins?

Bitcoin is the most popular cryptocurrency in the world, many people would like to become its lucky owner. Here are some ways to do it:

– Bitcoin faucets. This is an absolutely free method to get coins. It lies in performing various simple tasks, such as decoding and entering captchas, clicks on advertising links, browsing advertisers` websites, etc. This work is absolutely simple, but it requires  patience. We want to remind you, that reward for such work is purely tokenistic and it is not possible to earn decent money from Bitcoin faucets.

– Mining. This method means investment into equipment. It can be completely different: you can organize home mining on graphics cards spending 2-3 thousand US dollars on it, or you can build a huge data center by investing hundreds of millions of US dollars into this enterprise. Thus the income should be directly proportional to the initial investment. Unfortunately, today cryptocurrency is so volatile that it is impossible to calculate how much profit Bitcoin mining will bring in 2019.

– Salary in crypto. Nowadays, the fact of getting salary in cryptocurrency is no longer supernatural. Yes, it is still uncommon, but it is far from single instance.

– Purchase. The most obvious way to get cryptocurrency is to purchase it. Nowadays, you can buy Bitcoin using a large number of services (exchanges, currency exchange offices, individuals, etc.).

3. What is needed in order to start BTC home mining ?

In general, this is rather a broad theme, but in this article we will only briefly run through the main points, without which home mining is impossible. So you need to:

  1. Buy equipment for mining (graphic cards or ASIC miners).
  2. Create a Bitcoin wallet. Without this it will be impossible to get coins.
  3. Select a mining pool. Nowadays the hash rate (total computing power of all the miners) of Bitcoin network is really huge, that is why the algorithm constantly increases its overall complexity. This is why it will be very difficult for one miner to open a new block even with sufficiently powerful equipment.
  4. Install a special software for mining.
  5. Follow the process and, if necessary, repair or replace the components.

You should also remember that mining equipment (especially ASIC-miners) make a noise and heat up while working, therefore installment of farms in a residential house is not a good idea.

4. What is cloud mining?

There is another way to start mining Bitcoins. This is a cloud mining. It does not involve physical contact of person with equipment. A user buys a certain amount of computing power at a large data center and immediately starts to get income from it. So, how is it better to mine Bitcoin, on your own or using cloud? Everyone will find his own answer. Definitely, profit of home mining will be higher, but cloud mining will ease your pain associated with farm maintenance. Someone is willing to pay for his or her comfort, but another one would prefer to do everything by independently, therefore, everyone decides on one’s own.

5. Which video adapters work best for Bitcoin mining?

Each particular video adapter has its own payback period, which directly depends on what is happening on the cryptocurrency market. 2019 has just started, so here is the list of the most cost-effective video adapters for BTC mining in 2018:

  • NVIDIA GTX 1080 TI.
  • NVIDIA GTX 1070 TI.
  • NVIDIA GTX 1070.
  • RADEON VEGA FRONTIER EDITION.
  • RADEON RX VEGA 56.
  • RADEON MINING RX 470.
  • NVIDIA P106-100 (GEFORCE GTX 1060).

6. How to calculate Bitcoin mining correctly?

Bitcoin rate is very volatile, network hash rate is also unstable, so, it is almost impossible to calculate exactly the mining profit. But there are convenient calculators which will help you to find out at least approximate numbers.

7. What does BTC rate depend on and what will happen next?

Bitcoin price varies in the trading range of USD 4000.00. Bitcoin emission is limited and it amounts to 21 million coins. Over 17 million ones have already been mined. But it is necessary to recall a double decrease in the remuneration for a found block, which occurs every 4 years. It is easy to calculate that over the next 30 years, more than 99% of all coins will be mined, and the remaining 1% will be mined over the next 100 years.

According to the laws of economics, this feature makes Bitcoin a very valuable and, most importantly, a limited resource. Now Bitcoin capitalization is about 70 billion US dollars, and it is absolutely a wasted number from the world scale perspective. Many market experts predict a great future for this coin, for example, John McAfee believes that 1 Bitcoin by December 2020 will be USD 1,000,000.00.

If to take a look at Bitcoin chart for the entire history, one can see approximately the same picture of what is happening: rapid growth, prolonged correction, stagnation after which the cycle repeats. Moreover, every time during the correction, the media “buries” Bitcoin, and the coin after some time again renews its previous records.

8. Conclusion

Bitcoin mining, as of the beginning of 2019, is not a very profit-making enterprise without major initial investment. Bitcoin mining should be considered more like an investment for the future, when BTC becomes a very scarce asset and its value can literally skyrocket. Well, we cannot do anything but wait and actively monitor the developments.

GMO Will Keep On Mining Bitcoins at a Different Location

One of the world’s largest IT companies, Japan-based GMO has published its monthly report regarding its mining activities and the profits coming from them.

We remind you:

Japanese GMO Releases a Monthly Update: What Has Changed As For Mining?

Based on the December’s document, the revenue from mining cryptocurrency has dropped down  significantly which implies that immediate measures must be taken.

One of the biggest pitfalls of mining is the amount of electricity consumed and its high price. Thus, GMO made a decision to relocate its main mining center into a different area, where electricity will cost way less.

We will relocate the mining center to a region that will allow us to secure less expensive power supply,” reads the report.

Moreover, the company refuted all the rumors regarding its alleged plans of giving up mining completely. Since 2017, when GMO first engaged into mining, it has earned massive profits and still sees potential in crypto.

As we may see in the statistical data, the mining reward for Bitcoin increased a lot in the last month of December, whereas Bitcoin Cash suffered a hard fall. But the crash of the crypto market and Bitcoin in particular could not be controlled by GMO and affected its business quite badly, making it “move houses”.

The Dark Overlord Threatens To Reveal The Truth of 9/11 Attacks Unless Ransom in Bitcoin is Paid

The Dark Overlord, a hacking group, famous for posting unreleased episode of TV series “Orange is the New Black” in April 2017, decided to resume its blackmailing, however, this time it is not just an entertainment company Netflix, but insurance companies which possess information about 9/11 attacks.

The hackers claimed that they had hacked several insurance firms, like Hiscox Syndicates Ltd, Lloyds of London, and Silverstein Properties. These companies insured World Trade Centers in New York. It is still unclear what kind of information was stolen, but the culprits are trying to capitalize on conspiracy theories around the 9/11 attacks.

We’ll be providing many answers about 9.11 conspiracies through our 18.000 secret documents leak from @HiscoxComms and others #thedarkoverlord #911hacked#hacking #leak #cybercrime
            — thedarkoverlord (@tdo_h4ck3rs) December 31, 2018

One of the companies confirmed that the hackers had breached and stolen a few files related to the the September 11 attacks. The spokesman of the Hiscox Group wrote in email:

“The law firm’s systems are not connected to Hiscox’s IT infrastructure and Hiscox’s own systems were unaffected by this incident. One of the cases the law firm handled for Hiscox and other insurers related to litigation arising from the events of 9/11, and we believe that information relating to this was stolen during that breach.”

The hacking group sent a set of emails to that firms where it stated that the companies had to pay ransom in Bitcoin or The Dark Overlord unlocked different sets of files and the hidden truth of 9/11 attacks would be exposed.

They also mentioned that they offered to sell the information on the famous dark web hacker forum KickAss, as well as invited several Chinese and Russian terrorist groups to make purchase.
