Bitcoin Explained

Want create site? Find Free WordPress Themes and plugins.

Bitcoin

Following the uncertainty of the current world and its unstable economy where currencies face great flux every day, a new economy was introduced under the alias Satoshi Nakamoto. Under the worlds infinite disarray, Bitcoin emerged as a decentralized and a digital cash system with regulated by almost no one.

This peer-to-peer networking system runs through electronic signatures and crypto graphics to generate currency- Bitcoins. Bitcoins are not only a form of currency but also a form of investment for some investors who keep these coins in hopes of an increase in their value and enjoy the opportunity cost.

Mining

Just like normal everyday cash, this currency doesn’t have to be printed and issued by the federals or the central banks. Bitcoins are generated through a process called ‘mining’. These coins are mined out of the system by giving complex and advanced mathematical problems for your computer to solve. The target is to generate a 64-digit number as an answer to that puzzle. When a system solves the given complex algorithm, it obtains a specific fraction of Bitcoins every time.

The bitcoin network automatically sets the difficulty level of the mine to be mine next. On average, there are around 25 Bitcoins mined every 10 minutes. During the process, only a set number of Bitcoins can be mined during a certain period. After every four years, this reward is halved. Currently, it is up to 12.5 Bitcoins for every mathematical problem solved.

Limited Supply

Fiat currencies have an unlimited supply and their value can be easily manipulated anytime by the regulatory bodies. Given its independent nature, Bitcoin has tightly restricted supply controlled by the underlying algorithm of the system. There is a set number of coins that can ever be mined ever. A total number of 21 million bitcoins exist in the system.

Bitcoin at its peak has managed to engage the market by over 2 million dollars. The lowest has been $2. Today the value roughly swifts around $9,000.

No economy supports the sudden fluctuations in the system. Too much too fast will result in the dropping of the value of the currency. Too much too slow will cause the economy to halt. Due to these reasons, Bitcoin has a self-stabilizing system to regulate the economy at the most favorable grounds.

Exchangers allow the holders to transfer and buy or sell these Bitcoin crypto coins among other users. One of the famous platforms is Bitstamp. This allows users to buy Bitcoins in fiat currency and also enables them to sell them to other potential users. Bitstamp enables users to store the coins too as e-wallets. But beware of the hackers, as they can dangerously destabilize these digital economies.

With the gradual growing influence of these cryptocurrencies in the world today, a lot of applications and platforms have shown loyalty to the Bitcoin. Platforms like WikiLeaks and WordPress have started accepting bitcoins as means of their payments and transaction currency.

MintChip

Inspired by the Bitcoin, the Canadian government has launched a similar cryptocurrency named, MintChip. This electronic currency is backed by the government, unlike the Bitcoin.

Is Cryptocurrency Still Great for GPU Makers?

Want create site? Find Free WordPress Themes and plugins.

On Thursday, an American technology company, Nvidia has announced its financial results which were remarkable. The company has revenues of $3.2 billion from January to April. But what’s the reason behind this profit?

gpu makers

Well, the value of ether and other cryptos recently soared up and created lots of demand for graphics cards – to mine them. Due to the upsurge in the demand, the price of few high-end graphics got doubled between the mid of 2017 to February 2018. It’s a matter of concern for the GPU makers of major graphics-card, as the most important market for them is eventually the gamers, not the miners.

The idea of graphics-card makers collecting hefty profits from the high prices, due to the mining demand doesn’t seem to be liked by the gamers. However, Nvidia accredited that cryptos have played an important role in boosting the financial outlook of the company.

What does Nvidia’s CFO have to say about it?

CFO of Nvidia, Colette Kress said:

Cryptocurrency demand was again stronger than expected, but we were able to fulfil most of it with crypto-specific GPUs, which are included in our OEM business at $289 million.”

The $298 million figure is around 10% of the revenue of Nvidia and it seems like it lessens the cryptocurrency influence on the bottom line of Nvidia. If a customer buys a graphics card at retail, Nvidia won’t be able to know if it’s being used for mining, gaming or something else. The same story goes for the main graphics-card of a rival, AMD, which released first-quarter results a few weeks ago. According to AMD, the sales related to cryptocurrency accounted for almost 10% of total revenue, which could be again understating its influence on the profits of AMD.

GPUs Value

It has been observed that the value of cryptocurrencies has been falling for the past few months. Also, the value of GPUs has also gotten a lot cheaper than it was before. AMD didn’t provide any specific projection for revenues related to blockchain in the second quarter, however, the spokesman of the company suggested that the rest of the year 2018, is going to be significantly below the first quarter sales.

If the price of cryptocurrencies still keeps dropping, it will end up in the form of awful results for the GPU makers. But if the price of cryptocurrencies falls really low, it’s clear that we won’t only see miners halting to buy new GPUs but, we would also see them selling the graphic-cards that they already had on the secondary market. The resulting graphics card surplus could exhort the value of graphics-card below MSRP — MSRP would be good news for gamers though it might be bad news for the companies that are trying to sell new GPUs.

The president of AMD, Lisa Su said that she wasn’t really anxious about the scenario.

“There are multiple currencies being used — People who are mining do go from one currency to another depending on what’s happening.”

She also added that customers can buy graphics-cards for both purposes; gaming and mining. They will be able to hold onto the graphics-card for the gaming purposes — in the case of mining becoming unprofitable. On the other hand, this analysis seems to be debatable. There’s no doubt that there are profusions of cryptos, but at the same time, there are some of them which are economically significant.

Ethereum’s ether is the most important and significant GPU-mineable so far, and the prices of cryptocurrency are strongly linked to it. So, if the value of ether drops, there’s a possibility that the value of other cryptocurrencies might also fall with it. There are many people who want to buy graphics-card for various applications, and there are a lot of those as well that have many of them (graphics-card). These individuals might hold onto one or two cards for the gaming purpose, however, if the price of cryptocurrencies falls quite low, lots of those cards will end up in the used GPU market. This will also make it hard for both AMD and Nvidia in selling their new cards.

Bitcoin Price accelerates beyond $2000

Want create site? Find Free WordPress Themes and plugins.

US markets are celebrating as Bitcoin price soars above $2000 for the first time in history. Bitcoin’s price has surged more than 100% this year and nearly 125% since hitting an annual low of $891.51 in late March. Due to the price recently hitting new heights, the price appreciation will increase dramatically as well.

 

Bitcoin Price accelerates

 

Growing trader interest

The advantage of such sharp price gains is the rising interest of traders as measured by trading volume at major exchanges. Both Kraken and Poloniex had reportedly announced that they were experiencing surging bitcoin transaction activity.

Bitcoin Price accelerates

 

 

A number of factors have been driving the rally:

  • Trading volumes of Japanese yen and Korean won have escalated and account for around 48.6 percent of trading, according to stats from website CryptoCompare. That’s thanks to a recently passed law that allowed retailers in Japan to begin accepting Bitcoin as a legal currency. Since then, Japan has been a big driver of bitcoin trade.
  • Bitcoin has acted as a safe option, in the past, for investors that worry about political instability and the performance of other asset classes.
  • A debate within the bitcoin community about the future of the technology behind Bitcoin known as the blockchain has been taking place. At the moment, Bitcoin transactions are taking an unusually long time to process and come with high transaction fees. There was fear at one point this could lead to the merging of two different cryptocurrencies but those doubts have largely subsided with an alternative, more acceptable option being put forward.

All these factors add up to the rise in Bitcoin’s value in the shortest of time. According to CoinDesk, several billion US dollars have flowed into bitcoin last week, bringing its market value to more than $37 billion. In the end, as Bitcoin grows to gain more popularity and accessibility around the globe, its price will continue to soar as high as it can go.
