The increasing popularity of Bitcoin is causing a prominent shortage in the supply of graphic cards. It is considered a key component of the digital currency system over the last few years.

The chief executive of JIB group of computers, known as a leading IT retail and computer gaming chain said that the price of graphic cards is also increasing since mid of May 2017.

Graphics cards are the main part of computer systems which used for mining the cryptocurrency like Bitcoin. People who invest in Bitcoin can get revenues on their investment from Bitcoin much faster than other investments. They can get returns of their investment within only 5 to 15 months.

A mining rig is a computer system which miners use for mining cryptocurrency. According to Mr. Somyot, people think investing in a mining rig is not very risky. They use minimum six graphic cards. At a price of almost 2940 USD, for a mining rig.

In gaming markets, the margin on graphic cards has also been increasing since the 2nd quarter this year, and it is about 2-3% to 8-10%. The graphic card companies need to reserve the cards to dodge a negative impact on gamers. In the markets, the demand for the graphics cards is also at a high point.

 

 

The most commonly used graphic card for Bitcoin are NVIDIA 1060 and 1070, and AMD 570 and 580. These were in short supply and causing a 20% price hike.

According to predictions, the higher prices will remain until October.

Don Sambandaraksa is a long time Bitcoin enthusiast associated with cryptocurrency since 2013 when the price of Bitcoin was at 40 USD, he said, these days Bitcoin may no longer be efficiently mined with CPUs or even GPUs (Graphics Processing Units).

He said people have made chips that could only do Bitcoin hashes, nothing else.

Mr. Don said, 1080Ti card’s price is about 700 USD and it can get a return on investment in almost 108 days. Over a year can make 2300 USD, an annual return on investment of about 300%. He said, as more people come to buy graphic cards then the less profitable they will be. Mr. Don also said it is a sign of the crazy levels of the profitability that mining offers.

Beginner’s Guide to Tor

Want create site? Find Free WordPress Themes and plugins.

Just a couple years ago, Tor was something known only by tech-geeks. However, since leaks about the surveillance strategies of US and UK spies have arisen, Tor has become a target of criticism, accusations of promoting a “dark web” of pedophiles, drug dealers, and arms traders.

 

What is Tor?

The Tor project is a non-profit association that allowed users to browse the internet anonymously. It is intended to stop individuals – including government organizations and partnerships – from knowing of your location or learning about your browsing traditions.

The Tor network conceals your identity by moving your traffic across various Tor servers while encrypting the traffic. This makes it almost impossible for anybody to recognize the source of the data or region of the web client.

Tor’s software package, the Tor browser bundle can be downloaded easily and does not require any setup procedure. Although, you’ll experience a much slower internet than usual due to the number of relays your data goes through.

 

Who created Tor?

It was originally developed by the US Navy and received 60% of its funding from the State Departments and Department of Defense, along with several other backing bodies.

When it was initially launched in 2002, the project’s main focus was on securing every internet users’ privacy from corporations over governments.

Related: How to use Tor browser on iPhone

Who uses Tor?

Tor users fall into four main groups:

  • Normal users looking to just keep their browsing activities concealed from websites and advertisers
  • Cyber-spying concerned users that do not want their personal information to be tracked by any corporation.
  • Journalists and activists in countries with restrictions on the internet.
  • Whistleblowers can leak information to journalists while maintaining their privacy and having the freedom to express their true opinions.

 

The dark side                

Regardless of all its perks, everything has its drawbacks as well. It is important to be fully aware of what you click on while browsing with Tor. While many sites are socially acceptable or legal for that matter, others are known for having disturbing content. Stumbling upon such a web page showcasing criminal behavior or anything of that sort could land you in serious trouble.

Additionally, along with cloaking your identity Tor is also able to host websites, which means these sites are only accessible by people on the Tor network. These are known as criminal sites or in more obvious words “the dark web”.  The FBI and NSA have tracked down many of such sites, promoting disturbing content, drug purchases, illegal arms trading and much more.

What’s next?

We’re in an era of free-flowing data available to us with just a click of a button. Moreover, the internet is expanding on a daily basis and its depths are still unknown. With Tor becoming more widely used by internet users, the FBI and NSA have become more persistent in attempting to crack the network. In the end, it all depends on the user and for what activities they use Tor.

Computing power is higher   

Bitcoin computing power is 2 046 364 Pflop/s. whereas, 500 supercomputer’s computing power is 274 Pflop/s.  you can see the difference of power computing networks. However, Bitcoin users are not performing fluctuating processes. But, only numeral calculus. How can we proceed? It is simple, infect,

A hash is equal to 6.35K numeral actions

A numeral action is equal to 2 variable fact actions, whereas,

A hash will be equal to 12.7K variable fact actions

So, if we use the rate of one hash that is the 12.7K flop, and analyze it with the network is 161 131 086 gh/s, we get the approximation of 10^9*161131086 H/s * 12700 = 2 046 364,7922 Petaflops.

Too much computing power, this power can b utilize during modelization process.

Background of Cryptocurrencies in China

We would have to go a couple of years back  to properly understand the situation cryptocurrencies are facing right now in China. According to the initial coin offering news few years back, Bitcoin had gained great popularity among the Chinese Citizens, prices were also going up steadily.

Concerned with the progress of Bitcoin and other cryptocurrencies,in December 2013 the People’s Bank of China along with some other ministries of China, published an official notice regarding Bitcoin. Originally this notice was meant to reduce or control the financial risk of Bitcoin. Several points were highlighted in that notice pertaining to the risks involved in the sale and purchase of cryptocurrencies.

initial coin offering news

Salient Features of Notice Against Cryptocurrencies

According to the above mentioned notice the People’s Bank of China strictly ordered that:

  • All companies offering Crypto-related services especially Bitcoins, must be registered with the relative government ministries.
  • Organizations dealing specially in Bitcoin-related services should implement necessary measures to prevent money laundering and other illegal activities.
  • Any kind of criminal activity such as fraud, money laundering and gambling etc should be reported instantly to the authorities.
  • Companies behind the deals of Bitcoin and all such services should educate the public about Bitcoin and the technology behind it. This measure will save the majority of laymen from frauds, and fake companies would not be able to mislead the public with misinformation.
  • Bitcoin can only be bought or sold in its original form and not to be exchanged with traditional currency at any cost.
  • Rather than money, cryptocurrency can be best defined as something that serves as a medium of exchange or a store of value.

China’s Latest Approach Against Cryptocurrency

The deputy governor of the People’s Bank of China Fan Yifei outlined objectives in protecting the yuan at the 2018 national video conference.  It was a serious effort dedicated to the major challenges faced by the Chinese monetary system in terms of Yuan.

In his statement Fan supported the development of a government based digital currency in order to protect the yuan against unofficial virtual currencies. However, as was done in the past, no specific policies against crypto currencies were offered this time.
