Around 2008, Satoshi Nakamoto founded Bitcoin. At the time, a paper was published through the Cryptography Mailing List. The first Bitcoin software client was released in 2009, and he collaborated with many other developers on the open-source team, careful never to reveal his identity. By 2011, the enigmatic Bitcoin founder had disappeared. His peers understood how valuable this cryptocurrency was, and worked feverishly to develop it to its maximum potential.

But here are the basics… a blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. By design, blockchains are inherently resistant to modification of the data, and serve as a public ledger of transactions between two parties. To date, the best analogy I’ve heard for blockchain compares it to a Google Doc:
The FBI shut down Silk Road on 2 October 2013. The alleged chief operator of the site, Ross William Ulbricht (also known as Dread Pirate Roberts) was charged with alleged murder for hire and narcotics trafficking violation. The agency confiscated over 26,000 bitcoins from different accounts on Silk Road, worth approximately 3.6 million US Dollars back then. Twenty days later, the FBI reported that they had seized 144,000 BTC thought to belong to Ulbricht.
The rundown: Bitcoin and all major currencies were down in the morning; HSBC joins the Series B financing round of enterprise blockchain technology Axoni; GoverMedia Plus Canada to acquire European cryptocurrency exchange EXMO; Leading European companies selects IBM to drive blockchain innovation; SIMBA Chain to provide its cloud-based blockchain-as-a-service platform to the U.S. Air Force; […] The post Bitcoin News Crypto Currency Daily Roundup November 14 appeared first on Market Exclusive.
Since all of the virtual currencies remain a speculative asset, investors should avoid buying them for their retirement portfolios, says Jason Spatafora, co-founder of Marijuanastocks.com and a Miami-based trader and investor. Cryptocurrencies made up less than 2 percent of his portfolio a few months ago, but he is no longer trading them because of the extreme volatility.
Bitcoin is a peer-to-peer virtual currency. This means that in order for a transaction to occur, no middle men or central authority is needed. You can send any amount of bitcoins to anyone living anywhere in the world, completely eliminating the need for traditional third parties like banks or money transmitters. The cryptocurrency also allows the bypassing of capital and AML restrictions.

The Bitcoin's meteoric rise in value and the relatively low risk of being caught stealing it have also combined to make the currency a huge target for cyber criminals. Smaller online exchanges that have skimped on security systems can be hacked. The Sheep Marketplace, for example, had 96,000 Bitcoins (worth $220 million) stolen earlier this year, as did GBL and Tradefortress. Criminals also routinely target internet-connected computers that store individual Bitcoin wallets, attacking them with everything from malware and phishing tactics to old-fashioned social engineering. And as recently as last November, thieves stole nearly a million dollars worth of Bitcoin from Bitcoin Internet Payment System (BIPS), a Denmark-based Bitcoin payment processor.
If you had started mining Bitcoins back in 2009, you could have earned thousands of dollars by now. At the same time, there are plenty of ways you could have lost money, too. Bitcoins are not a good choice for beginning miners who work on a small scale. The current up-front investment and maintenance costs, not to mention the sheer mathematical difficulty of the process, just doesn't make it profitable for consumer-level hardware. Now, Bitcoin mining is reserved for large-scale operations only.  
The rapid price increase of Ethereum has not only attracted investors but developers too. Ethereum has tens of thousands of developers in its open source community, each contributing to the many layers of the “Ethereum stack”. This includes code contributions to the core Ethereum clients, second layer scaling tech and the “decentralized applications” (dApps) that are built on top of the platform. The appeal of Ethereum to developers is unique in that it was the first platform to allow anyone in the world to write and deploy code that would run without the risk of censorship. The community of developers which have formed around these core principles have led to the creation of technologies that could not have existed without the inception of Ethereum, many of which were never predicted. Some of the major use-cases of Ethereum so far have been:
By mining, you can earn cryptocurrency without having to put down money for it. That said, you certainly don't have to be a miner to own crypto.  You can also buy crypto using fiat currency (USD, EUR, JPY, etc); you can trade it on an exchange like Bitstamp using other crypto (example: Using Ethereum or NEO to buy Bitcoin); you even can earn it by playing video games or by publishing blogposts on platforms that pay its users in crypto. An example of the latter is Steemit, which is kind of like Medium except that users can reward bloggers by paying them in a proprietary cryptocurrency called Steem.  Steem can then be traded elsewhere for Bitcoin. 
Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining.[70]
A notable example of this was FBI’s shutdown of the ‘’Silk Road’’ marketplace. The website had over 10,000 products for sale, 70% of which were drugs that are illegal in most countries. Around 340 different varieties of drugs were offered on the site. The site functioned as an ‘’Ebay for drugs’’, connecting buyers with sellers and not doing any dealing themselves.
Like we mentioned previously, in order to send or receive bitcoins you will need to have a bitcoin address. You can get a bitcoin address either by downloading the bitcoin client or by getting an online wallet. The two most popular btc clients are Bitcoin-qt and Multibit. The main difference between these two clients is in the size of the block chain that needs to be downloaded. If you decide to go with Bitcoin-qt, have at least 10 Gigabytes free space on your hard drive for the block chain. As Bitcoin-qt is the ‘’official’’ bitcoin client, if you can spare 10 GB, go for this option. Here’s a page that has step by step instructions on installing Bitcoin-qt.
Ethereum-based customized software and networks, independent from the public Ethereum chain, are being tested by enterprise software companies.[83] Interested parties include Microsoft, IBM, JPMorgan Chase,[49][84] Deloitte,[85] R3,[86] Innovate UK (cross-border payments prototype).[87][88] Barclays, UBS and Credit Suisse are experimenting with Ethereum blockchain to automate Markets in Financial Instruments Directive (MiFID) II requirements.[89]
Ethereum's blockchain uses Merkle trees, for security reasons, to improve scalability, and to optimize transaction hashing.[100] As with any Merkle tree implementation, it allows for storage savings, set membership proofs (called "Merkle proofs"), and light client synchronization. The Ethereum network has at times faced congestion problems, for example, congestion occurred during late 2017 in relation to Cryptokitties.[101]
Waves is a LPoS (Leased Proof of Stake) cryptocurrency that is fully premined . When users mine Waves, they receive the transaction fees in exchange for maintaining the Waves Blockchain. In a Leased Proof of Stake environment, users can choose to be a full node and use the balance from other users to stake Waves for a greater profit or to lease their Waves balance to a full node in order to receive transaction fees without having to run a full node. This system allows anyone to participate in the Waves network maintenance.

Feel free to use this thread to say 'Hi, I'm new!' or 'Hi, I'm not!'. If you have a question, feel free to comment and ask it below. But first make sure you are fully synchronized and have a look at FAQ on Ethereum Stack Exchange. Need help finding resources for beginners or have lots of questions and don't know where to start?

Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto.[23]

Bitmex is the leading bitcoin margin trading site. Users can trade cryptocurrency derivatives with up to 100x leverage. Pairs include BTC/USD, Yen, Monero, Ripple, Dash, and Ethereum. Bitmex CEO Arthur Hayes has used his experience as an equity derivatives trader for Deutsche Bank to design, build, and maintain exactly the type of platform that users are looking for. Granted that this platform is for experienced and seasoned traders. Beginners should avoid trading coins here without knowing the implied volatility risks.

At this point, the actual mining begins. In essence, each miner now tries to demonstrate to the rest of the network that his or her block of verified payments is the one true block, which will serve as the permanent record of those 2,000 or so transactions. Miners do this by, essentially, trying to be the first to guess their block’s numerical password. It’s analogous to trying to randomly guess someone’s computer password, except on a vastly larger scale. Carlson’s first mining computer, or “rig,” which he ran out of his basement north of Seattle, could make 12 billion “guesses” every second; today’s servers are more than a thousand times faster.


A lot of you have asked me whether trading bitcoin is better than buying it. The answer depends on your goals, and experience of bitcoin trading. If you're looking to hold bitcoin as a long-term investment and check the price intermittently, it's better to buy bitcoin. This way you benefit from a small, one time exchange fee and the assurance that you hold a physical bitcoin in your wallet which can be spent at various retail stores.

The reward for doing so -- a miner's fee if you will -- is payment in that block's coin. The payment is based on how much their hardware contributed to solving that puzzle. Where do the coins come from? By design, that's exactly how the coins are created. The block is solved and coins and distributed fairly to miners. This increases the coin's supply.
Btc.sx offers a 10 to 1 leveraged product based on BitStamp’s data feed. Similarly to Ava Trade, Btc.sx adds around 10$ to the spread at BitStamp. You will need a deposit of at least 0.01033 of a bitcoin in order to trade at Btc.sx. At current bitcoin prices of $638, this amounts to around 6.3$. Btc.sx is dually incorporated in England and Singapore. The exchange currently accepts only bitcoin deposits, no fiat currency deposits are allowed.
Additionally, national governments and exchanges are mulling over regulation of the whole realm of cryptocurrencies. Japan has recently introduced legislation to protect users after Tokyo-based Bitcoin exchange Mt Gox collapsed in 2014. Similarly, introducing taxation such as capital gains tax on Bitcoin sales may also impede the cryptocurrency industry.
AVA Trade is a forex broker that offers bitcoin trading through a CFD. Two bitcoin CFDs are available, Bitcoin Mini and Bitcoin Weekly. The Bitcoin Weekly CFD has a 20 to 1 leverage and expires every Friday at 21:00 GMT. The Bitcoin Mini only has a 2 to 1 leverage but doesn’t expire. Both contracts are using data from BTC-E and AVA Trade adds around 10$ premium on top of the exchange spread. You can find more about the bitcoin trading conditions here. Here’s a snapshot of AvaTrade’s MT4.
In this section we’ll go over several options for trading bitcoin on margin. We’ll also outline the options to short the virtual currency. Before we go any further, a caution is in order. Bitcoin prices are highly volatile. Prices rose from a low of 195.50 on November 1st to a high of 1,090 by November 30th 2013. From here, the btc price crashed to a low of 420 on December 18th, only to go back up and retest the 1,000 level in January of this year. One bitcoin is currently worth 825.88 on btc-e. The chart below demonstrates this volatility.

Buterin and Joseph Poon (a co-author of Bitcoin's Lightning Network whitepaper) announced in 2017 their plan to launch a scaling solution called Plasma which creates "child" blockchains to the "main" parent blockchain.[98] The plasma project has skeptics; specifically, Vlad Zamfir (Ethereum's lead researcher on proof of stake) has publicly questioned the plasma project's viability.[98]

After much debate, the Ethereum community voted and decided to retrieve the stolen funds by executing what’s known as a hard fork or a change in code. The hard fork moved the stolen funds to a new smart contract designed to let the original owners withdraw their tokens. But this is where things get complicated. The implications of this decision are controversial and the topic of intense debate.
