Hi, could you review Coinut? It is a Singapore registered exchange platform, and it claims that they using C++ so that having a smooth experience (not too sure though). It also support fiat currency (USD & SGD). They are having a low transaction fee for takers and FREE for makers tho. Seems like the founder are graduated from National University of Singapore (NUS - pHD in CS) and he is also one of the early members of Litecoin developer. Please do check it out and review! As sometimes I really struggle which to use.
Indeed, for a time, everything seemed to come together for the miners. By mid-2013, Carlson’s first mine, though only 250 kilowatts in size, was mining hundreds of bitcoins a day—enough for him to pay all his power bills and other expenses while “stacking” the rest as a speculative asset that had started to appreciate. By then, bitcoin was shedding its reputation as the currency of drug dealers and data-breach blackmailers. A few legitimate companies, like Microsoft, and even some banks were accepting it. Competing cryptocurrencies were proliferating, and trading sites were emerging. Bitcoin was the hot new thing, and its price surged past $1,100 before settling in the mid-hundreds.
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]
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.
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.”
Demo Account: Although demo accounts attempt to replicate real markets, they operate in a simulated market environment. As such, there are key differences that distinguish them from real accounts; including but not limited to, the lack of dependence on real-time market liquidity, a delay in pricing, and the availability of some products which may not be tradable on live accounts. The operational capabilities when executing orders in a demo environment may result in atypically, expedited transactions; lack of rejected orders; and/or the absence of slippage. There may be instances where margin requirements differ from those of live accounts as updates to demo accounts may not always coincide with those of real accounts.

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.

Bitcoin bear trend comes to a close with the final wave of capitulation which has effectively shaken out all weak hands. The only people in the market right now are optimists. Money flow into the market at this point will directly result in price appreciation without much resistance. All of this is going to happen fast. Keep calm and fill your bags.

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.

HIGH RISK INVESTMENT WARNING: Trading foreign exchange and/or contracts for difference on margin carries a high level of risk, and may not be suitable for all investors. The possibility exists that you could sustain a loss in excess of your deposited funds and therefore, you should not speculate with capital that you cannot afford to lose. Before deciding to trade the products offered by BitcoinTradingWorld you should carefully consider your objectives, financial situation, needs and level of experience. You should be aware of all the risks associated with trading on margin. BitcoinTradingWorld provides general advice that does not take into account your objectives, financial situation or needs. The content of this Website must not be construed as personal advice. BitcoinTradingWorld recommends you seek advice from a separate financial advisor.
The best bitcoin exchange is needed for serious and professional bitcoin traders. Bitcoin security must be impeccable. Banking relationships must be sound and reliable. The trading engine must be fast. Order types must be advanced. And profits must be able to be multiplied with Bitcoin margin trading so you can leverage long bitcoin positions or short bitcoin positions.

As can be seen from the data on this page, Ethereum’s price has been enormously volatile and therefore highly unpredictable over the short-term. However, longer-term trends are easier to predict, with fundamental metrics such as the total number of developers, community discussion and GitHub pull requests indicating a more accurate future price trend. Other methods to predict the price of Ethereum include metrics such as Network Value to Transaction ratio (NVT ratio) and the relative prices between coins. The method that we find most interesting is in that of the Ethereum-based prediction market, Augur. These predictions source the “wisdom of the crowd” to determine the likelihood of an outcome occurring and provide a significant level of insight into the market sentiment.
The Ethash proof of work algorithm is memory hard, you'll need at least 1+GB of RAM on each GPU. I say 1+ because the DAG, which is the set of data that's being pushed in and out of the GPU to make parallelisation costly, will start at 1GB and will continue growing indefinitely. 2GB should be a good approximation of what's needed to continue mining throughout the year.

Coinexchange supports loads of altcoins, meaning that to buy cryptocurrency or cryptocurrencies is easy. Their stated goal is to provide traders with new ICOs, and a secure and safe exchange on which the altcoins available can be traded. Their 'About Us' section though, is lacking as it doesn't provide information about the platform’s licensing status or its history. Community chatter at Bitcoin Talk demonstrates people’s numbness to state a straightforward opinion about where to put this operation yet. That being said, the bitcoin exchange offers a highly accurate bitcoin exchange rate for every coin.
While it’s still early days, Mist, MetaMask and a variety of other browsers look set to make blockchain-based applications accessible to more people than ever before. Even people without a technical background can now potentially build blockchain apps. This is a revolutionary leap for blockchain technology that could bring decentralized applications into the mainstream.
In order to send or receive bitcoins, all you need to have is a bitcoin address and internet access. You only need to be online long enough for the transaction to process. Similarly to traditional bank accounts, you can receive bitcoins to your bitcoin address even if you’re offline. When you want to ‘’collect’’ your coins however, you’ll have to find an internet connection.

For us non-miners, getting Bitcoin is now easier than it was a year ago. Now, one only needs to be in a right country to purchase and sell Bitcoins, where exchanges legally act as intermediaries for currency transactions — something that also protects your funds from being mismanaged by external and internal attacks. These exchanges instantly convert your Bitcoin into USD or other fiat currency, and based on the price fluctuations between these two, one can simultaneously sell and purchase their holdings and make good profits — a process we know as arbitrage (explained further below)

Quality of customer support. For the customers, receiving answers to their questions is always an indicator of the quality of work. Making everything possible to ensure fast processing of your inquiries, the customer support at CEX.IO works 24/7. And each member of the support team goes through the carefully designed intensive training to be able to deal with any possible issues. In such a way the platform may often be identified as the most responsive among Bitcoin exchanges.

The latest CryptoDredge Nvidia GPU miner version 0.10.0 available for both Linux and Windows comes with improved performance in a number of the supported algorithms and adds support for the HMQ1725 algorithm. The hashrate improvements cover the X22i, BCD and X17 as well as the Skunkhash performance boost for the 0.9.7 if you have missed that update as well. Currently the CryptoDredge 0.10.0 is the fastest Nvidia GPU miner for the X22i algorithm used by the SUQA project, so if you are mining SUQA coins at the moment on Nvidia mining rigs with other software you should definitely switch to he latest CryptoDredge. Do note that the CryptoDredge miner supports only Nvidia GPUs and is a closed source software that comes with 1% built-in developer fee and with binaries available for both Windows and Linux (CUDA 9.1/9.2/10.0).
For all the peril, others here see the bitcoin boom as a kind of necessary opportunity. They argue that the era of cheap local power was coming to an end even before bitcoin arrived. One big reason: The region’s hydropower is no longer as prized by outside markets. In California, which has historically paid handsomely for the basin’s “green” hydropower, demand has fallen especially dramatically thanks to rapid growth in the Golden State’s wind and solar sectors. Simply put, the basin may soon struggle to find another large customer so eager to take those surplus megawatts—particularly one, like blockchain mining, that might bring other economic benefits. Early data from Douglas County, for example, suggest that the sector’s economic value, especially the sales tax from nonstop server upgrades, may offset any loss in surplus power sales, according to Jim Huffman, a Douglas County port commissioner.
Use a Bitcoin relay to convert a 2-way peg: the bitcoin relay is a piece of code that allows you to sidechain a bitcoin into ethereum. This means that you can use Bitcoin's native limited scripting capability to lock a bitcoin into a contract that is directly connected to an ethereum contract, which can then issue an ethereum based token that is guaranteed to be backed by bitcoin. The relay is under development and as implementations are tested and proved to be secure, we will list them here.
Over Labor Day weekend (Sept 2017), needing a break from my startup Harvey, I had the choice of binge watching Narcos 3 on Netflix or taking a deep dive into cryptocurrencies. Since learning about the impressive $100M fundraise by Coinbase at a $1.6B valuation, I was been eager to understand their product suite a little better and discover where there might be a new income opportunities, so I jumped in and went deep.
Using Ethereum, you can create a contract that will hold a contributor's money until any given date or goal is reached. Depending on the outcome, the funds will either be released to the project owners or safely returned back to the contributors. All of this is possible without requiring a centralized arbitrator, clearinghouse or having to trust anyone.
