The issue of security has been a fundamental one for bitcoin since its development. On one hand, bitcoin itself is very difficult to hack, and that is largely due to the blockchain technology which supports it. As blockchain is constantly being reviewed by bitcoin users, hacks are unlikely. On the other hand, though, the fact that bitcoin itself is difficult to hack does not mean that it's necessarily a safe investment. There does exist potential for security risks at various stages of the trading process.

In the most specific sense, a paper wallet is a document containing all of the data necessary to generate any number of Bitcoin private keys, forming a wallet of keys. However, people often use the term to mean any way of storing bitcoins offline as a physical document. This second definition also includes paper keys and redeemable codes. A paper key is a single key written on paper that is used multiple times like a wallet (this is strongly discouraged). A redeemable code is a single key intended to be funded and "redeemed" only once: these are commonly used for gifts and as part of physical Bitcoin coins/notes.But storing bitcoins on paper wallets is not safe unless very strict security precautions are undertaken during their initial preparation

Ukrainian legislators should separate the regulation of crypto mining from the legal status of cryptocurrencies. The new approach was proposed by the chairman of an important parliamentary committee who criticized law enforcement agencies for cracking down on crypto miners.If Ukraine decides to address mining separately, some crypto regulations may be adopted sooner than expected. Similar suggestions have been made in Russia, where legalizing cryptocurrencies has divided institutions but most officials agree that crypto mining can be legalized and regulated. Even Russia’s Central Bank, that has opposed the legalization of cryptocurrencies like bitcoin, recently announced it would allow crypto mining

Satoshi Nakamoto is the founder of Bitcoin and initial creator of the Original Bitcoin client. He has said in a P2P foundation profil that he is from Japan. Beyond that, not much else is known about him and his identity. He has been working on the Bitcoin project since 2007.His involvement in the Bitcoin project had tapered and by late 2010 it has ended. The most recent messages reportedly indicate that Satoshi is "gone for good".He left some clues about why he is doing this project with the inclusion of the following text in the Genesis block, "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks.

In the context of cryptocurrency mining, a mining pool is the pooling of resources by miners, who share their processing power over a network, to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A "share" is awarded to members of the mining pool who present a valid partial proof-of-work. Mining in pools began when the difficulty for mining increased to the point where it could take years for slower miners to generate a block.

Promoting Bitcoin and cryptocurrency is not an easy task these days, but there are some interesting ideas to be found all over the world.This are the way to promote bitcoin.
1. Promote Bitcoin is by getting tiny amounts into the hands of as many people as possible without too much friction. Most Meetup groups and university initiatives hand out small amounts of Bitcoin at every turn, which will also boost the number of mobile wallet installations in the long run.

2. Bitcoin clothing goes a long way, as it is the first thing people see when encountering others. Spreading the world of Bitcoin and cryptocurrency with T-shirts, hoodies, and hats is always a positive thing. But don’t forget the Bitcoin socks either, which make great gifts.

3. Create Bitcoin water bottles because this may seem like an insignificant project, but a lot of consumers are well aware of the labels on their beverages. A beautiful black and white Bitcoin label on a water bottle will certainly attract some attention.

1. If you’re knowledgeable about Bitcoin, enthusiastic about the cryptocurrency industry in general and willing and able to share your knowledge, then you can also earn Bitcoin by doing so. The amount that can be earned by writing about Bitcoin varies, but can be quite lucrative depending on the level of expertise that you have on the subject.
2. There are potentially significant earnings to be made in Bitcoin lending, but there is also significant risk. Bitcoin lending tends to operate through intermediary websites such as Bitbond and the concept is as simple as it sounds. You act as a bank, lending your Bitcoin to another person at a certain level of interest. Because the market is unregulated the levels of interest are generally much higher than the standard bank rate meaning that there is a potential for high returns.
3. Mining Bitcoin is the process by which new coins are created. Mining is carried out using certain computer programmes and utilises the processing power of the miner’s computer. At its inception, Bitcoin mining was relatively simple and the earliest miners were able to mine thousands and thousands of Bitcoin with limited expenditure.
4. There is huge potential to make money on trading in Bitcoin, but it takes a level of expertise and knowledge about the market in the same way that trading on any other financial market does. In addition, the cryptocurrency market is extremely volatile and therefore may not suit everybody’s tastes and risk appetite.

In addition to financial benefits, there are several elements that secure bitcoin from theft. Cryptography controls the creation and transfer of a cryptocurrency, and the protocols underlying bitcoin have proven to be robust. Bitcoin's use of a distributed ledger known as blockchain gives owners a record of all their transactions that cannot be tampered with because there is no single point of failure.However, this hasn't stopped attackers from exploiting vulnerabilities within bitcoin exchanges or wallets -- the software used for storing bitcoins on computers or smartphones. Bitcoin exchanges are not regulated by the government, and they generally do not provide enough insurance and security to be used to store money in the same way as a bank.

For real converting your cash to bitcoin can get you bitcoins within a couple of hours.Buying bitcoins with cash is also private.Many of the exchanges below do not require you to verify your identity or provide sensitive personal details.Many exchanges are simply trying to steal your personal information (like your password).I suggest using the exchanges listed below or doing research before buying from any exchange.

1. Local Bitcoins
2. BitQuick
3. CoinsBase
4. Bittrex

As you know , ranking in bitcointalk thread has been changed after 24th Jan , a new feature called " merit" has been added to profile .What is merit ?
•You get merit points when someone sends you some for one of your posts. Additionally, when someone sends you merit points, half of those points can be sent by you to other people.
what has changed in ranking?
•In addition to activity, everyone now has a merit score, and you need both a certain activity level and a certain merit score in order to reach higher member ranks.

I'm hoping that this system will increase post quality by:
•This forcing people to post high-quality stuff in order to rank up. If you just post garbage, you will never get even 1 merit point, and you will therefore never be able to put links in your signature, etc.
•Highlighting good posts with the "Merited by" line.

As a trader, one of the most important things you can do to improve your chances of success is to approach trading as a business. A successful trading business requires a strategic plan that covers your actual business and your actual trading. Your business plan will include things like short and long-term goals, the amount of capital you have available for the business and how you will set up your office. Your trading plan includes the details of trading: what you will trade and how you will trade it. Your plan should be so objective and concise that you could hand it over to another trader and they would be able to execute it exactly.It’s important to understand that your trading plan is not simply a set of rules that you think will work, a list of set-ups that you are somehow fond of, or someone else’s plan. A good trading plan is one that you have researched, tested on historical data, tested in a live market and continue to evaluate at regular intervals.

For a justifiable reason: governments would prefer not to see contending monetary standards. They debilitate their imposing business model to make cash and control the monetary framework and the economy.In reality, the reason China is the primary huge government to make such move isn't a mischance. China more than some other nation needs to have firm control of its managing an account framework, and distribute credit as indicated by a political plan. This implies a contending money like the Bitcoin would debilitate its political framework.

It should be teach.Because for economists and business school professors, Bitcoin and other digital tokens have raised questions about the nature of money. The first lecture in the Berkeley class, for example, considered the development of Bitcoin against the history of money.Several business school classes are also focusing on the decentralized methods of record keeping and decision making introduced by Bitcoin.Bitcoin is given credit for creating the first blockchain, a ledger of transactions that is updated by a network of computers without relying on any central company or government.

Actually, the reason China is the first big government to take such action isn’t an accident. China more than any other country wants to have firm control of its banking system, and allocate credit according to a political agenda. This means that a competing currency like the Bitcoin would threaten its political system. Why not crush it sooner than later? While it is still unclear whether the Chinese government will achieve its real objectives, one thing is clear: the buzz for the digital currencies is gone, at least for now.

Gold is respected throughout the world for its value and rich history, which has been interwoven into cultures for thousands of years. Coins containing gold appeared around 800 B.C., and the first pure gold coins were struck during the rein of King Croesus of Lydia about 300 years later. Throughout the centuries, people have continued to hold gold for various reasons.

1. Unlike paper currency, coins or other assets, gold has maintained its value throughout the ages. People see gold as a way to pass on and preserve their wealth from one generation to the next.
2. Gold has historically been an excellent hedge against inflation, because its price tends to rise when the cost of living increases. Over the past 50 years investors have seen gold prices soar and the stock market plunge during high-inflation years.
3. In previous years, increased wealth of emerging market economies boosted demand for gold. In many of these countries, gold is intertwined into the culture. India is one of the largest gold-consuming nations in the world; it has many uses there, including jewelry.
4. Gold should be an important part of a diversified investment portfolio because its price increases in response to events that cause the value of paper investments, such as stocks and bonds, to decline. Although the price of gold can be volatile in the short term, it has always maintained its value over the long term. Through the years, it has served as a hedge against inflation and the erosion of major currencies, and thus is an investment well worth considering.

A hardware wallet is a special type of bitcoin wallet which stores the user's private keys in a secure hardware device.They have major advantages over standard software wallets:

1. private keys are often stored in a protected area of a microcontroller, and cannot be transferred out of the device in plaintext.
2. immune to computer viruses that steal from software wallets
3. can be used securely and interactively, as opposed to a paper wallet which must be imported to software at some point
4. much of the time, the software is open source, allowing a user to validate the entire operation of the device

Bitcoin, like gold has value because people believe it has value. If people value something, it is “valuable” to them. Often we attribute value to things simple because we can do something with it that cannot be done otherwise.

1. Bitcoin is different than fiat (Government money) in that there is nobody forcing you to use it (to pay your taxes, etc), or preventing you from using it (as in capital controls, etc).
2. Bitcoin is neutral: it is indifferent to where you were born, where you live, who you are, what you are buying, etc.
3. Bitcoin has technical properties which make it much more flexible, programmable and reliable in certain situations, so it has properties which might make it more valuable to someone who needs those.
4. Most of the value today is speculation because people believe it could replace many sections of our economy currently controlled by banks.
