Clever though it is, the system has weaknesses. One is rapid consolidation. Most mining power today is provided by “pools”, big groups of miners who combine their computing power to increase the chance of winning a reward. As mining pools have got bigger, it no longer seems inconceivable that one of them might amass enough capacity to mount a 51% attack. Indeed, in June 2014 one pool, GHash.IO, had the bitcoin community running scared by briefly touching that level before some users voluntarily switched to other pools. As the bitcoin price continues to fall, consolidation could become more of a problem: some miners are giving up because the rewards of mining no longer cover the costs. Some worry that mining will become concentrated in a few countries where electricity is cheap, such as China, allowing a hostile government to seize control of bitcoin. Others predict that mining will end up as a monopoly—the exact opposite of the decentralised system that Mr Nakamoto set out to create.
A high-level summary of Claymore rig health can be monitored using tail -f on a logfile of watchclay output. The summary includes overall hashrate, slowest GPU, shares accepted and rejected by the mining pool, the temperature of the hottest GPU, and total amps drawn.
Ethereum uses Proof of Work (PoW) concept, which means you as an ether miner need to solve complex equations to become a part of the network and earn ether. As more and more miners are joining the network, it is becoming difficult to solve problems.
The Bitcoin Gold GPU Miner 2000 H/s from Ethereumminer.eu  is a pre-built mining rig that offers the potential of a pretty excellent profit. While values may fluctuate, you could see this rig paying for itself after not long at all. Especially as it has recently had a price cut – something of a rarity with mining devices which usually see price rises! This rig can also be customised to your needs and budget.
The DAO crowdfunding project has stirred up a resurgence in the Ether price, which had fallen and hit a patch of sideways activity following a previous rally. At press time, CoinMarketCap.com reports the Ether price at $14.05 USD.
It’s just as inaccurate to calculate the rise in difficulty without calculating the rise in price. Also, when Ethereum goes to PoS, GPU mining efforts can just be transferred to other coins and algorithms.
What do you want to optimise for? Lowest upfront cost per unit hashrate? Lowest ongoing cost (upfront + electricity)? Best hashrate per unit electricity? Lowest heat (and electricity) per unit hashrate?
Mining contractors provide mining services with performance specified by contract, often referred to as a “Mining Contract.” They may, for example, rent out a specific level of mining capacity for a set price at a specific duration.
I assume cards with 8+6pin would draw 150W+75W from the pcie cables so the powered riser may have less stress? But that would mean the riser needs its own power input cable which can be scarce depending on the PSU setup.
As more miners join the network, the mining difficulty increases, and therefore you receive less Ethereum for the amount of energy spent to solve one problem. As data suggests, Ethereum block difficulty increased from 171 TH/s(1 Trillion hashes per second) to 1714 TH/s in 6 months in 2017.
The HD 7990 was released in 2013 and is harder to purchase from stores as this series has been superseded by the R9 series released in 2015. Internally, the HD 7990 with 6Gb RAM consists of two AMD HD 7970 GPUs with 3Gb RAM each packaged together.

Cryptocurrency mining is a big buzz topic in technology these days and many people have started mining cryptocurrencies. In 2018, Ethereum smashed its long-term $400 ceiling, and reached more than $1,000, which makes it one of the most popular cryptos for mining.

A reasonable cost of power is approximately 10 cents per kwh. This is below the national average for retail power rates in the U.S. To run a mining rig you will likely pay at least 10 cents per 1,000 watts run for each hour. This means one full day of mining comes with an electricity cost of $2.40. We will also use the block reward and block difficulty from January of 2018 as our base point. And we assume mining with a single rig is only reasonable when working with a mining pool. Some mining pools take up to 10 percent of your earnings, but some of the best only take 1 percent. For that reason, we’ve pick a modest 1.5 percent.
Many people have started mining cryptocurrencies so more and more graphic cards are going out of stock. GPU manufacturers have struggled to meet demands from miners and this has driven up the prices of particularly efficient cards.
