The Difficulty Of Bitcoin Mining Explained

The difficulty of mining process grows as more effort is spent on mining and more bounty hunters join the race. Initially, having a home PC was enough to plunge in Bitcoin mining, then savvy mining gurus moved to utilizing the computing power generated by top gaming graphics cards, but finally the niche has was occupied by digital miners – the devices designed for mining purposes exclusively. At first miners were produced basing on reprogrammed chips, but not so long after application the units based on specific integrated circuits, ASICs, characterized by stunning performance and relatively low power consumption hit the shelves.

For example, the power of a single graphics card Radeon HD 7990 (Nvidia’s solutions are mainly not suitable for mining) equals 1.2 GHs per second at a few hundred watts of energy consumption, while a modern ASIC device, e.g. System Red Fury priced at $125 generates 2.5GHs per second and consumes as little as 2.5 watts. Modern mining implies using ASIC devices, otherwise the affair is commercially unprofitable. Alternatively, one can purchase the necessary amount of GHs via special platforms, e.g. CEX.IO.

Once the miner is purchased the operational expenses are overwhelmingly represented by electricity bills in exchange for Bitcoins. The cost of mining a single Bitcoin may vary from $30 to $600, depending on the equipment used and electricity tariffs. In 2011, buying a top gaming card for mining paid off in about two weeks, but with the growing complexity of the calculation to produce Bitcoins the method is almost useless.

bitcoinMining pool concept

Therefore, miners began to gather in the pools that combine several tens, hundreds or thousands of miners in a single unit: in the case the unit is discovered and mined its share is distributed in accordance with the size of the contribution to the common cause. The system perceives the pool as a miner, producing hundreds of GHs per second, but in practice it is a main server, distributing tasks to miners included in its pool. Unlike solo mining, pool mining generates cash pretty quickly, but in relatively small portions.

In recent months, the media began to cover more and more stories about the unique Bitcoin farms, the largest of which are located in Hong Kong. November, 25 was the launch date of the factory with hardware cooled with liquid cooling, the capacity of which amounted to 4% of the total power in the network or 35 THs per second. It produces about 26 Bitcoins per day, which at the time of writing is equal to tens of thousands of dollars. In April 2013, Kaspersky Lab reported the discovery of a trojan that secretly turns users’ computers in Bitcoin generators.

Best Investment Plans – How To Select The Most Appropriate?

To choose suitable best investment plans that could implement your ideas and aims  is a decisive solution because main embodied into reality decisions should be accepted only by you. Also you would be the sole who will tote all the risk related with the investment implementation.That‘s why your  making plan must look rationally reasoned and moreless perfect. Never choose for higher risk investment even if seems that you operate with  sufficient cash amount.

There are several rules of investment that you always keep in consideration:

  • No one investment plan whatever it may seems to be perfect is   absolutely secured. Always existing a certain degree of risk;
  • Never invest blindly in any plan having no comprehension on complete  material of the plan;
  • Never choose for higher risk investment even if seems that you operate with  sufficient cash amount.

What you should to do is to fix main goals and principles before implement those best investment plans. You should raise the following question such as “What is that you wish to attain through your investment?” and then  try to concentrate on your own determined goals. Here would like present several options for indicated goals :

  • Safety – when the person selecting for this goal he expects that the risk related with the defined investment must be minimal. This indicator (safety) of defined investment is highest.
  • Income – this type of investment aim defines that person is targeting a stable stream of income through his investment by making some regular payment operations.
  • Growth – here the individual expects for long period investment. Also the risk here is more higher because a person might get a dividend on the invested amount or might not.
  • Speculation – it is the most risky investment. Here there are existing chances  to get higher return in short period but there are also possibilities for small or higher loss. In this case you can even forfeit the all  investment summ.

Also are important below mentioned points that you have rely :

  • Never invest all the money that you have.
  • Search for tip from a professional and trustworthy advisor.
  • Before investing create a plan of it.

Hope this information would be useful to all concerned persons pursuing to realise suitable solution in investing process.It would be great if such information has a possibility to introduce a fresh investor or  young person who intend to realise available funds through the investing.

Leeds The Muslim

Leeds has a strong Muslim community with nearly 3% of Islam adherents from the entire population. The city houses a number of mosques and organisations with Mosque Jinnah, Leeds Grand Mosque, Makka Masjid and Bilal mosques, the Islamic Cultural Centre of Leeds, Leeds Islamic Organisation, Center for Islamic Studies at the University of Leeds and so on. Muslims represent an active part of the populace with a great reputation and respect from both authorities and residents. All mosques organised lessons and lectures on Islamic sciences such as the Qur’an, hadith, sira, Fiqh and etc. The places of cultural interest are scattered throughout the city, thus you may want to consider various Leeds hotels options when planning your trip to the city.

Leeds Central Mosque Jinnah is the first and the oldest mosque of Leeds, erected in 1958. Subsequently, in 1974 and 1982 the territory of the mosque complex was expanded. In 1980, the government of Leeds provided a grant for mosque sports hall construction, where nowadays sports and cultural events, as well as weddings, meetings and conferences take place.

Leeds Grand Mosque

The largest mosque in the city was converted from a church in 1994 due to the financial contribution made by Muhammad bin Saif Al Nahyan from Abu Dhabi (UAE). The complex’s main hall open space is used for experiments in human echolocation field.

Makka Masjid

Makka Masjid was built in 2003; until then, the Muslims of Leeds rented two houses. To date, Makka Masjid is one of the most beautiful active mosques in Leeds.

Bilal Mosque

Founded in 1982, Bilal occupied the building of a church. The mosque launched a number of educational courses, training young men and women in various Islamic disciplines. Bilal supports the local sports center.

The Maternity Dress Of Your Dreams

Maternity Wedding DressIf you want to look majestic and solemn on your wedding day, take your time and select a maternity wedding dress carefully. Remember that you will be wearing a dress for a long time, so it should in no way hamper your movability. The models tailored from light and flowing fabrics will make a pregnant bride look like a queen. An elegant addition – a diadem instead of a veil, will certainly emphasise your brilliant look.

Choosing the right fabric

Providing the desired comfort for the expectant mother is possible using the models sewn from lightweight and flowing material. For this reason, pregnant women are best to abandon dresses with corset, which is explained by the fact that these wedding dresses made of heavy taffeta and come with multilayered skirts. Actually, you should better make a choice in favor of dresses with the addition of chiffon, organza or flying and flowing matt silk. All the women who are expecting a baby radiate special energy, and such materials will give ethereal and light feeling. Remember that the material of the dress should be chosen with care, because even the most famous and savvy wedding dress salon will hardly be able to add cardinal changes to the bride’s dress at the supreme moment.

The cut of the sleeves should be special

The wedding dresses for pregnant women have a tiny but very important detail you should pay attention to – the sleeves. The primary requirement is not to overdecorate the sleeves; the trend of the season consists in adding straps, which adds intriguing nudity. If you are on 4-5+ month of pregnancy, the wedding dress should not look similar to the sleeves, because the tummy may become more noticeable, while puffed sleeves may spoil the look by making you look thicker. Check some wedding fashion magazines to find a bunch of photos of wedding dresses for pregnant women, and to see how designers emphasise the sleeves.

Scrap Metal Industry In Europe

Scrap metals are considered to be waste products intended to be processed in order to enter the manufacturing cycle over again. The trend of growing interest in scrap metals is booming not only in Europe and the United States; Turkey, India, China and dozens of other countries are actively buying scrap metal in huge volumes. The explanation is pretty easy to find: scrap metal is way much cheaper than raw iron or copper.

Honestly, the Eastern and Western attitudes towards scrap metals processing are fundamentally different. Therefore, Europeans nourish interest in maintaining free trade of scrap: import and export rates are currently on the crest of a wave here. Since a savvy European scrap metal dealer is interested in searching for prospective opportunities, the number of imported and exported scrap is typically close to be equal. This indicates a high stability of the market and progressive development of market relations.

Western European countries sell scrap in many other countries: Turkey, the Netherlands, Austria, Switzerland and nearly 30 states more to be mentioned. In Germany, France and the UK scrap metal is consumed in higher volumes in comparison with raw minerals. By the way, Germany is the European leader in scrap metal harvesting and processing, as well as export.

In accordance with a research, carried out in the University of Brussels, European dumps will store almost four billion tons of ferrous metal in the coming 25 years. The lion’s share of this volume will be comprised of cars. Scientists forecast that over the 25 years the number of the vehicles produced will outperform the number of cars ever produced before. The consumption boom, according to experts, will naturally be more noticeable in more developed economies.

Konstantin Novoselov About Graphene

Nobel Laureate in Physics Konstantin Novoselov believes that graphene, for investigation of which he and Andrew Geim received a prestigious award, will be applied in the production of high-frequency transistors. Graphene is already available for individual entrepreneurs in the UK (the price ranges from 700 to 2300 pounds).

Now everyone is talking about graphene mainly positively: the material has unique physical chemical properties; it is expected it will revolutionise the world of electronics. This is the first known to man two-dimensional material that conducts electricity as well as copper; thus it grants an opportunity to create touch screens, solar sails for space vehicles, flexible electronic devices and many more.

However, the method for producing graphene, which was pioneered by Geim and Novoselov, initially did not find support in the scientific community. They used graphite rods and duct tapes, glued and then sticking to obtain material with a thickness of just one atom. It was believed that the layers of this thickness will be deformed.

Currently, Novoselov is asked one basic question regarding a better solution for the whole world: is graphene really better than its ‘precursor’, silicon, which is already used in the manufacture of transistors? The question of how the new technology will make another step forward to really take advantage of graphene has to be answered yet.

As mentioned, graphene for private engineering purposes is already available. The world’s first supplier of this material is the company Graphene Industries, registered in Manchester, where Geim and Novoselov live and work. Moreover, the industry is entered by ambitious brain tanks – the graphene companies like 2-DTECH provide guidance on how to integrate the neoteric material, thus accelerating the commercialisation process. The company representatives claim that graphene uses are numerous, and even today the innovative businesses can derive considerable benefits from its use.

‘Right now, we are collaborating with the owner of Graphene Industries, Peter Blake, who sells graphene for studies of biological objects in the transmission electron microscopes’, says Novoselov.

Currently, work is underway on the use of graphene in the creation and super-capacious phenomenally quickly-recharged batteries, particularly for electric vehicles, laptops and mobile phones. ‘Well this is a completely new area, and the results achieved so far do not mean that the full potential is used’, says Novoselov.

Even though the author of the revolutionary invention fails to forecast when will the practical application of graphene technology be used massively and worldwide, Novoselov is still quite optimistic. ‘If I was asked a year ago, I probably would have said ‘never’, but the last year was marked by a major breakthrough in the field of mass graphene production, so at the moment I’m much more optimistic about the practical application of this material’.

According to him, a good indicator of possible applications, it was not what people think in the laboratory, but what big companies plan. ‘The plans for the application of graphene by Samsung suggested experiments with further development to the commercial samples of touchscreen-displays back in 2012, however, the progress is not yet appreciable’, Novoselov says.
