Smart contract is just a phrase used to describe computer code that can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Because smart contracts run on the blockchain, they run exactly as programmed without any possibility of censorship, downtime, fraud or third party interference.

Good morning, traders. Binance completed the update to its platform overnight and Bitcoin price continues to feel pressure. With CBOE expiry later today, traders must remain vigilant if they are interested in trading this area as we could likely see price pop up at/near that time. However, we may see more movement down toward $6100 first. Notably, 1D OBV has ...


There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as bitcoin result in high up-front costs to miners in the form of specialized hardware and software.[87] Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media. This prevents the cryptocurrency from being spent, resulting in its effective removal from the markets.[88]
Launched in 2015, Ethereum is a decentralized software platform that enables SmartContracts and Distributed Applications (ĐApps) to be built and run without any downtime, fraud, control or interference from a third party. The platform is also the basis for its own virtual currency, Ether. Ethereum is not just a platform but also a programming language (Turing complete) running on a blockchain, helping developers to build and publish distributed applications. The potential applications of Ethereum are wide ranging.
Bitcoin trading really is not much different to any other asset you can trade - maybe just a bit more volatile, but that is a good thing if you want to trade it! You will have to devide whether or not to trade the asset (bitcoin) itself or some derivative (financial “bet”). I recommend the latter as it allows you to participate in both bull and bear markets. If you simply buy the asset (Bitcoin) you can only participate in rising prices. The derivative also allows you to leverage your position. Having that said : LEVERAGE IS A DOUBLE SIDED SWORD! Whenever you trade with leverage make sure you are mentally ready to lose everything that is on your trading account (in other words: make sure not to put too much money on your trading account). Moreover, do not trade something you do not understand!
Swing trading tries to take advantage of the natural “swing” of the price cycles. Swing traders try to spot the beginning of a specific price movement, and enter the trade then. They hold on until the movement dies out, and take the profit. Swing traders try to see the big picture without constantly monitoring their computer screen. For example, swing traders can open a trading position  and hold it open for weeks or even months until they reach the desired result.
As soon as a miner finds a solution and a majority of other miners confirm it, this winning block is accepted by the network as the “official” block for those particular transactions. The official block is then added to previous blocks, creating an ever-lengthening chain of blocks, called the “blockchain,” that serves as a master ledger for all bitcoin transactions. (Most cryptocurrencies have their own blockchain.) And, importantly, the winning miner is rewarded with brand-new bitcoins (when Carlson got started, in mid-2012, the reward was 50 bitcoins) and all the processing fees. The network then moves on to the next batch of payments and the process repeats—and, in theory, will keep repeating, once every 10 minutes or so, until miners mine all 21 million of the bitcoins programmed into the system.
Sure. As discussed, the easiest way to acquire Bitcoin is to buy it on an exchange like Coinbase.com. Alternately, you can always leverage the "pickaxe strategy". This is based on the old saw that during the 1848 California gold rush, the smart investment was not to pan for gold, but rather to make the pickaxes used for mining. Or, to put it in modern terms, invest in the companies that manufacture those pickaxes. In a crypto context, the pickaxe equivalent would be a company that manufactures equpiment used for Bitcoin mining. You can look into companies that make ASICs miners or GPU miners. 
The attraction then, as now, was the Columbia River, which we can glimpse a few blocks to our left. Bitcoin mining—the complex process in which computers solve a complicated math puzzle to win a stack of virtual currency—uses an inordinate amount of electricity, and thanks to five hydroelectric dams that straddle this stretch of the river, about three hours east of Seattle, miners could buy that power more cheaply here than anywhere else in the nation. Long before locals had even heard the words “cryptocurrency” or “blockchain,” Miehe and his peers realized that this semi-arid agricultural region known as the Mid-Columbia Basin was the best place to mine bitcoin in America—and maybe the world.
In February 2014 the world's largest bitcoin exchange, Mt. Gox, declared bankruptcy. The company stated that it had lost nearly $473 million of their customers' bitcoins likely due to theft. This was equivalent to approximately 750,000 bitcoins, or about 7% of all the bitcoins in existence. The price of a bitcoin fell from a high of about $1,160 in December to under $400 in February.[67]

A custom built computer that has been specifically designed for mining. Do you remember when we mentioned initial start up costs, and not being able to use your own computer for mining? This is because you will not be able to use your computer whilst you are mining, making it much more ideal to have a separate one completely. Laptops and handheld devices are not advisable to use, as they simple do not have enough power to generate any sort of income.
The trick, though, was finding a location where you could put all that cheap power to work. You needed an existing building, because in those days, when bitcoin was trading for just a few dollars, no one could afford to build something new. You needed space for a few hundred high-speed computer servers, and also for the heavy-duty cooling system to keep them from melting down as they churned out the trillions of calculations necessary to mine bitcoin. Above all, you needed a location that could handle a lot of electricity—a quarter of a megawatt, maybe, or even a half a megawatt, enough to light up a couple hundred homes.
Hey, where’s Bitsane here? I guess you would like to add it to the list, don’t you mind? I am not an expert to state the pros and cons but I can share some personal opinion. You can get confused there sometimes cause me for instance - I can’t get all that rules and f.a.q.s and special info to know that youngsters get on with easily. But what I am relieved with is the rate of low costs of fees for transactions to put your money in and out (for I can’t stand that crazy part of giving a shitty load of money from your own pocket to the user fees god-knows-what-for). And there are also pretty quick to get through, which is suitable in urgent cases that occur currently. So, here is the exchange I strongly recommend to include in the list. Please consider.
Many also fear that the new mines will suck up so much of the power surplus that is currently exported that local rates will have to rise. In fact, miners’ appetite for power is growing so rapidly that the three counties have instituted surcharges for extra infrastructure, and there is talk of moratoriums on new mines. There is also talk of something that would have been inconceivable just a few years ago: buying power from outside suppliers. That could mean the end of decades of ultracheap power—all for a new, highly volatile sector that some worry may not be around long anyway. Indeed, one big fear, says Dennis Bolz, a Chelan County Public Utility commissioner, is that a prolonged price collapse will cause miners to abandon the basin—and leave ratepayers with “an infrastructure that may or may not have a use.”
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]
Dangers of volatility – Bitcoin is the most volatile of all assets, including the stock and gold markets. Whilst volatility brings with it opportunity to day trade bitcoin for a profit, it also brings with it doubt and unpredictability. For example, in June 2017 bitcoin was being traded at $2,983. It then lost 30% in value and crashed down to $1,992, only to climb up to $4,764 in September, boasting a 139% gain. You must ensure your bitcoin day trading strategies take into account the uncertainty.

Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion of the total mining power on the network.  Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own.  For instance, a mining card that one could purchase for a couple thousand dollars would represent less than 0.001% of the network's mining power.  With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse.  The miner may never recoup their investment.  The answer to this problem is mining pools.  Mining pools are operated by third parties and coordinate groups of miners.  By working together in a pool and sharing the payouts amongst participants, miners can get a steady flow of bitcoin starting the day they activate their miner.  Statistics on some of the mining pools can be seen on Blockchain.info.
Just because miners want power doesn’t mean they get it. Some inquiries are withdrawn. And all three county public utilities have considerable discretion when it comes to granting power requests. But by law, they must consider any legitimate request for power, which has meant doing costly studies and holding hearings—sparking a prolonged, public debate over this new industry’s impact on the basin’s power economy. There are concerns about the huge costs of new substations, transmission wires and other infrastructure necessary to accommodate these massive loads. In Douglas County, where the bulk of the new mining projects are going in, a brand new 84-megawatt substation that should have been adequate for the next 30 to 50 years of normal population growth was fully subscribed in less than a year.
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]
Conversely, if one were to take the super-long view and, say, bought a few shares in 2012 at a sub-$100 price point, even with Bitcoin dropping half its peak value, that investor would still theoretically make over a 600 percent return on his investment just by waiting. Granted, the sub $100 days are likely now over, what with the currency's new-found stardom so we'll have to wait and see how the market plays out.
No one was more surprised than the miners themselves. By the end of 2017, even with the rapidly rising difficulty, the per-bitcoin cost for basin miners was around $2,000, producing profit margins similar to those of the early years, only on a vastly larger scale. Marc Bevand, a French-born computer scientist who briefly mined in the basin and is now a tech investor, estimates that, by December, a hypothetical investor who had built a 5-megawatt mine in the basin just four months earlier would’ve recovered the $7 million investment and would now be clearing $140,000 in profit every 24 hours. “Nowadays,” he told me back in December, miners “are literally swimming in cash.”

AS LONG AS WE REMAIN ABOVE THE LONG TERM TREND LINE FROM A TECHNICAL STANDPOINT WE ARE STILL BULLISH SO IF WE DO GO JUST $250 DOLLARS LOWER AND CLOSE BELOW 5500 THEN YES WE HAVE BROKEN THE TRENDLINE AND ARE NOT VERY BEARISH BUT DONT PANIC WE ARE NOT THERE YET AND AS LONG AS THIS HOLDS ABOVE THE TRENDLINE WE COULD SEE A MASSIVE RALLY INCOMING SO WATCH CLOSELY AND ...
This is the most popular Bitcoin pair in the world. Bitcoin uses peer-to-peer technology to operate with no central authority or banks; managing transactions and the issuing of Bitcoins is carried out collectively by the network. Bitcoin is open-source; its design is public, nobody owns or controls this cryptocurrency and everyone can take part. Bitcoin price grew significantly within a short period of time making the BTC/USD pair quite popular among active traders and investors. Through many of its unique properties, Bitcoin allows exciting uses that could not be covered by any previous payment system.
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:
Despite the fact that your bet on British pounds earned you an 11.11% profit (from $1,000 to $1,111.11), the fluctuation in the bitcoin to U.S. dollar rate means that you still sustain a loss of .016 bitcoin, or -0.8%. (initial deposit of 2 bitcoins — 1.984 bitcoins = .016 bitcoin). However, had the bitcoin to U.S. dollar exchange rate changed to 1 bitcoin = $475, you would realize a profit from both the forex trade and the bitcoin exchange. In other words, you would have received ($1,111.11/$475) = 2.339 bitcoins, a profit of 16.95%.
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 silence of the Chinese authorities was seen as a subtle acceptance signal by market participants. The situation didn’t last long however. On December 7th, The People’s Bank of China barred financial institutions from buying or selling virtual currency or Bitcoin related products. The Bank also demanded that businesses stop with the practice of pricing their products in Bitcoins. BTC/USD opened the day at $906.50 on BTC-E. After the news hit the wires, bitcoin prices crashed from to a low of $551 in only 9 hours, a fall of 39%.
Izabella Kaminska, the editor of FT Alphaville, has pointed out that criminals are using Ethereum to run Ponzi schemes and other forms of investment fraud.[106] The article was based on a paper from the University of Cagliari, which placed the number of Ethereum smart contracts which facilitate Ponzi schemes at nearly 10% of 1384 smart contracts examined. However, it also estimated that only 0.05% of the transactions on the network were related to such contracts.[107]

Bitcoincharts is the most popular website for following the current bitcoin price. The site provides a rundown of all major btc exchanges by volume. You can also arrange the markets to only display the Euro or the Japanese Yen versus bitcoin on the different exchanges. Like the name says, the website also offers charts with several popular technical indicators. The choice of timeframes ranges from 1 minute all the way to the Weekly TF. Plus, you get to see the current market depth at the different exchanges.
There is only a limited amount of crypto coins that can be mined, and once these have all been mined, there will simply be no more. So, for example, there are 21 million Bitcoins in total, and once these have all been mined, they will be the only coins in circulation – no further Bitcoins will be added to the system. This is not just apparent to Bitcoins though, and refers to all other Cryptocurrencies.
In addition to lining the pockets of miners, mining serves a second and vital purpose: It is the only way to release new cryptocurrency into circulation. In other words, miners are basically "minting" currency. For example, as of the time of writing this piece, there were about 17 million Bitcoin in circulation. Aside from the coins minted via the genesis block (the very first block created by Bitcoin founder Satoshi Nakamoto himself), every single one of those Bitcoin came into being because of miners. In the absence of miners, Bitcoin would still exist and be usable, but there would never be any additional Bitcoin. There will come a time when Bitcoin mining ends; per the Bitcoin Protocol, the number of Bitcoin will be capped at 21 million. (Related reading: What Happens to Bitcoin After All 21 Million are Mined?)
According to BitPay, a Bitcoin Payment Service Provider, as of November 2013 there are over 14,000 merchants currently accepting bitcoins. Two years ago this number stood at few hundred. The number of transactions facilitated by Bitpay increased tenfold in 2014 and crossed the 50,000 mark in November. The payment processor said that 6,296 bitcoin transactions occurred on Black Friday last year, up from only 99 transactions the year prior.
Poloniex was once the best cryptocurrency exchanges, before competitors like Bittrex starting offering superior services. Nevertheless Poloniex went through extremely fast traffic growth since the demise of its rival Cryptsy in 2016, and especially since the recent altcoin bubble of early 2017. Traffic has grown from 33 million monthly visits in November 2017 to 66 million in December 2017. Poloniex has the nicest trading interface out there, both for mobile and desktop users this will work wonders. Please note that because Poloniex is a pure "crypto" exchange, it is not possible to deposit government (fiat) currency. You'll need to first buy bitcoin elsewhere, and then deposit it to be able to tade. I've written a full analysis of Poloniex, further exploring the founders, users, security, fees, history, and alternatives.
If your objective is to earn substantial money as a second income, then you are better off purchasing cryptocoins with cash instead of mining them, and then tucking them away in the hopes that they will jump in value like gold or silver bullion. If your objective is to make a few digital bucks and spend them somehow, then you just might have a slow way to do that with mining.
This dramatic volatility attracted global attention with the mainstream media running near-daily reports on the price of Ether. The publicity generated has been a major boon for the ecosystem, attracting thousands of new developers and business ventures alike. In 2018 the amount raised through Ethereum-enabled ICOs reached almost $8bn, increasing from just $90m in 2016. While the price of Ethereum has faced extreme volatility over the years, it is this volatility which has driven interest. After every boom and bust cycle, Ethereum comes out the other side with a fundamentally stronger platform and a broader developer community backing it. These fundamental improvements would suggest a positive long-term outlook on the price of Ethereum.

IE… I have 50 ETH , and want to buy a ‘widget’ for 25 ETH given a particular set of circumstances (it works, or the temperature is >10c tomorrow). I agree with a seller on the conditions of a contract, and we ‘create’ a contract on an Ethereum platform, with appropriate sign-offs and verification. This could be 2 steps, or it could be 1000 steps. Once established in the ‘smart contract’, if it is indeed >10c tomorrow, the contract automatically shifts 25 ETH to your account and ships me my widget. The results are recorded in the blockchain.
