In May 2018, Bitcoin Gold (and two other cryptocurrencies) were hit by a successful 51% hashing attack by an unknown actor, in which exchanges lost estimated $18m.[72] In June 2018, Korean exchange Coinrail was hacked, losing US$37 million worth of altcoin. Fear surrounding the hack was blamed for a $42 billion cryptocurrency market selloff.[73] On 9 July 2018 the exchange Bancor had $23.5 million in cryptocurrency stolen.[74]
It takes a (global) village to raise a blockchain. The live network and the community of open source developers contribute significantly to this effort. They continuously refine and harden the Ethereum platform, helping it get faster at responding to industry demands for the value propositions it offers. These investments of time and resources speak to their faith in Ethereum governance and the value that businesses and developers see in its capabilities. – Joseph Lubin, CEO of Consensys
Other projects like OmiseGo are now building on top of Ethereum, using this as a parent chain and providing scaling solutions such as Plasma to really push the boundaries of what is currently possible with Ethereum, other such projects like Raiden are also important in the long run as they allow transaction speeds to ramp up, whilst there are a range of other projects to speed up bitcoin exchanges and bitcoin applications such as the lightning network, Ethereum too will be using sharding along with other side chain projects to allow for a much more efficient and expansive system for everyone to participate.
The high rollover cost also makes leveraged trading at Btc.sx problematic. The currency rollover cost for my position was 0.0094 of a bitcoin, that’s 8.8 US Dollars, far too high for a 1,000 usd position in my opinion. Because the company only allows deposits and withdrawals in bitcoin, it has largely avoided the US Dollar deposit/withdrawal issues encountered by other btc exchanges. Btc.sx does allow US clients.

Keep in mind, Coinbase charges a 3.99% processing fee for all credit card transactions. I’d recommend using a credit card that gives you at least 3% cash back so you can offset some of the fees (I’ll cover the fee structure in more detail in the next section). You can use PayPay for selling currency, buy not buying currency; for PayPal the funds are available instantly but have lower payout limits. The bank account is usually your best bet.
Btc exchanges are a somewhat safer place for your bitcoins compared to online wallets because they keep most coins in what is known as ”cold storage”. Usually over 90% of the bitcoins deposited on an exchange are kept offline. A small 5 to 10% reserve is kept onsite for immediate redemption purposes. There are plenty of guides online on how to store/secure bitcoins, go over them. It’s always safer to take care of this process yourself then to trust a third party with a substantial amount of bitcoins.
What you may not know is the technology surrounding mining isn't just limited to consumer graphics cards. We’re beginning to see PC game platforms that allow you to mine when you’re away from your system, and exchange that digital currency for new games. There are even new Pokemon GO-style games hitting the app stores that are outdoor scavenger hunts with cryptocurrency as the ultimate treasure.

A very widely used type of price graph, Japanese candlesticks are based on an ancient Japanese method of technical analysis, used in trading rice in 1600’s. Each “candle” represents the opening, lowest, highest, and closing prices of the given time period. Due to that, Japanese Candlesticks are sometimes referred to as OHLC graph (Open, High, Low, Close).
Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last[92] and links it to Tulip mania.[93] American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending.[94] In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'.[95] "Bitcoin just shows you how much demand for money laundering there is in the world," he said.
Hey! Please follow this technical analysis step-by-step and hopefully You get better at trading! Appreciate it and appreciate my hard work by hitting the LIKE button, because someone asks money for this but I only ask a Like ;) Because I start to make my technical analysis on Coinbase than I thought I make this a bit educational post and hopefully You find ...

In 2016 a decentralized autonomous organization called The DAO, a set of smart contracts developed on the platform, raised a record US$150 million in a crowdsale to fund the project.[41] The DAO was exploited in June when US$50 million in Ether were taken by an unknown hacker.[42][43] The event sparked a debate in the crypto-community about whether Ethereum should perform a contentious "hard fork" to reappropriate the affected funds.[44] As a result of the dispute, the network split in two. Ethereum (the subject of this article) continued on the forked blockchain, while Ethereum Classic continued on the original blockchain.[45] The hard fork created a rivalry between the two networks.[46]
A few miles from the shuttered carwash, David Carlson stands at the edge of a sprawling construction site and watches workers set the roof on a Giga Pod, a self-contained crypto mine that Carlson designed to be assembled in a matter of weeks. When finished, the prefabricated wood-frame structure, roughly 12 by 48 feet, will be equipped with hundreds of high-speed servers that collectively draw a little over a megawatt of power and, in theory, will be capable of producing around 80 bitcoins a month. Carlson himself won’t be the miner; his company, Giga-Watt, will run the pod as a hosting site for other miners. By summer, Giga-Watt expects to have 24 pods here churning out bitcoins and other cryptocurrencies, most of which use the same computing-intensive, cryptographically secured protocol called the blockchain. “We’re right where the rubber hits the road with blockchain,” Carlson shouts as we step inside the project’s first completed pod and stand between the tall rack of toaster-size servers and a bank of roaring cooling fans. The main use of blockchain technology now is to keep a growing electronic ledger of every single bitcoin transaction ever made. But many miners see it as the record-keeping mechanism of the future. “We’re where the blockchain goes from that virtual concept to something that’s real in the world,” says Carlson, “something that somebody had to build and is actually running.”
Interestingly, both resistance and support levels are usually set around round numbers e.g. 10,000, 15,000 etc. The reason for that is that many inexperienced traders tend to execute buy or sell orders at round price points, thus making them  act as strong price barriers. Psychology also contributes a lot to support and resistance levels. For example, until 2017, it seemed expensive to pay $1,000 per Bitcoin, so there was a strong resistance level at $1,000. Once that level was breached, a new psychological resistance level was created: $10,000.
The Depth Chart right below the Price Chart shows a detailed visual representation of the bid and ask prices over a range of prices. You can increase or decrease the price range for the chart by using the plus or minus buttons at the top of the chart. The price in the middle of the chart is the midpoint price between the best bid and ask prices. Moving the cursor over the prices will allow you to select a price in which you can create an order. Clicking the price will fill in the buy/sell price for you automatically in the left sidebar. This chart is a useful to see how close buyers are from sellers in their ask/bid prices; the greater the surface area under the curve, the more bids there are at that price.
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.
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.
According to Ethereum, it can be used to “codify, decentralize, secure and trade just about anything.” One of the big projects around Ethereum is Microsoft’s partnership with ConsenSys which offers “Ethereum Blockchain as a Service (EBaaS) on Microsoft Azure so Enterprise clients and developers can have a single click cloud based blockchain developer environment.”
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:
As a cryptocurrency, Bitcoin is generated through the process of "mining"—essentially using your computer's processing power to solve complex algorithms called "blocks." You earn around 50 Bitcoins once a block has been decrypted. The catch? Depending on how powerful your CPU is, solving a single block can take a year or more. Another means of obtaining Bitcoin is to simply buy it, exchanging physical currency for digital at a Bitcoin exchange like Mt. Gox or Bitstamp, or through a service like BitInstant.

Goldman Sachs says blockchain technology “has the potential to redefine transactions” and will “change everything”. But anyone who claims to fully understand how blockchain works, and is not named Satoshi Nakamoto, is probably lying to you. And anyone who claims to be Nakamoto himself, is probably also lying to you. Fortunately, just like the internet, you don’t need to know how blockchain works to use it.
