Largest crypto mining farm heroes
The hype around cryptocurrencies seems to peak and trough as frequently as new developments emerge in the Huawei trade ban saga , it seems so significant at the time but the excitement inevitably wains shortly after. But the global bitcoin fever came as an unwelcome event to some - namely Iran's national power grid. Iran's Energy Ministry shut down two cryptocurrency mining farms last week due to the undue strain they, and a rising number of farms like them, have placed on Iran's critical infrastructure. So, when you consider that the two farms shut down by the Iranian government were running around 1, high-powered crypto miners between them, it becomes a little easier to fathom the scale of demand placed upon the national grid. Bitcoin mining farms that run hundreds and sometimes thousands of machines at once are among the most profitable ways of mining bitcoin.

Bitcoin mining likely uses more energy than it takes to keep New Zealand's lights on. The recent upsurge in the price of Bitcoin seems to have finally awakened the world to the massively destructive environmental consequences of this bubble. These consequences were pointed out as long ago as by Australian sustainability analyst and entrepreneur Guy Lane, executive director of the Long Future Foundation. In recent months, the Bitcoin bubble has got massively bigger and the associated waste of energy is now much more widely recognised.
In essence, the creation of a new Bitcoin requires the performance of a complex calculation that has no value except to show that it has been done. The crucial feature, as is common in cryptography, is that the calculation in question is very hard to perform but easy to verify once it's done. At present, the most widely used estimate of the energy required to "mine" Bitcoins is comparable to the electricity usage of New Zealand, but this is probably an underestimate.
If allowed to continue unchecked in our current energy-constrained, climate-threatened world, Bitcoin mining will become an environmental disaster. In the early days of Bitcoin, the necessary computations could be performed on ordinary personal computers. But now, "miners" use purpose-built machines optimised for the particular algorithms used by Bitcoin. With these machines, the primary cost of the system is the electricity used to run it.
That means, of course, that the only way to be profitable as a Bitcoin miner is to have access to the cheapest possible electricity. Bitcoin mining today is concentrated in China , which still relies heavily on coal. Even in a large grid, with multiple sources of electricity, Bitcoin mining effectively adds to the demand for coal-fired power. Bitcoin computers run continuously, so they constitute a "baseload" demand, which matches the supply characteristics of coal.
More generally, even in a process of transition to renewables, any increase in electricity demand at the margin may be regarded as slowing the pace at which the dirtiest coal-fired plants can be shut down. So Bitcoin mining is effectively slowing our progress towards a clean energy transition — right at the very moment we need to be accelerating.
A widely used estimate by Digiconomist suggests that the Bitcoin network currently uses around 30 terawatt hours TWh a year, or 0. If the current high price is sustained for any length of time, Lane's estimate will be closer to the mark, and perhaps even conservative. The cost of electricity is around five cents per kilowatt hour for industrial-scale users.
Miners with higher costs have mostly gone out of business. As a first approximation, Bitcoin miners will spend resources nearly all electricity equal to the price of a new Bitcoin. However, to be conservative, let's assume that only 75 per cent of the cost of Bitcoin mining arises from electricity. Roughly speaking, each MWh of coal-fired electricity generation is associated with a tonne of carbon dioxide emissions, so a terawatt-hour corresponds to a million tonnes of CO2.
Digiconomics estimated that Visa is massively more efficient in processing transactions. A supporter of Bitcoin, Carlos Domingo, hit back with a calculation suggesting that the entire global financial system uses about TWh per year, or three times as much as the Diginconomics estimate for Bitcoin.
As a defence, this is far from impressive. First, as we've seen, if the current high price is sustained, total annual energy use from Bitcoin mining is also likely to rise to TWh. More importantly, the global financial system serves the entire world. By contrast, the number of active Bitcoin investors has been estimated at 3 million.
Almost all of these people are pure speculators, holding Bitcoin as an asset while using the standard financial system for all of their private and business transactions. Another group is believed to use Bitcoin for illicit purposes such as drug dealing or money laundering , before converting these funds into their own national currency.
The number of people who routinely use Bitcoin as a currency for legitimate transactions might be in the low thousands or perhaps even fewer. With the current threat of climate change looming large globally — this constitutes an unthinkably large amount of energy consumption. The disastrous nature of Bitcoin's energy consumption should not lead us to abandon the associated idea of blockchain technology altogether.
There are alternatives to the "proof of work" method of validating changes to the blockchain, such as "proof of importance", which is analogous to Google's page ranking systems. Projects such as Gridcoin are based on calculations that are actually useful to science.
But these ideas are in their infancy. For the moment, the problem is Bitcoin and how to deal with it. There is no obvious way to fix the inherent problems in its design. The sooner this collective delusion comes to an end, the better. Originally published in The Conversation.

Why cryptocurrency mining is a challenge in India
While different types of cryptocurrency are produced in different ways, more bitcoin are brought into the market through mining. Bitcoin mining is done by computers, all over the world, running algorithms and complicated math equations to solve a block. Blocks make up a blockchain, which makes up bitcoin. Once the transactions are pulled into a block, miners all over the world compete to solve it. The first miner or group of miners to solve the block earns 6. Les said the process is really just guessing, and in order to have the most guesses, miners need to have the latest and greatest mining software and hardware. Les said Texas is an ideal state for bitcoin mining, for a few reasons.

Here are the most important news, trends and analysis that investors need to start their trading day:. The Nasdaq's rise Monday brought the index within 2. Tech stocks got a boost from a continued easing in the year Treasury yield. The rapid spike in market rates in , most recently a run of month highs , knocked growth stocks, many of them tech names, as higher borrowing costs erode the value of future profits and squeeze market valuations. Credit Suisse announced several high-level staff departures and proposed a cut to its dividend in the fallout from the Archegos Capital saga. Late last month, Credit Suisse was forced to dump a significant amount of stock to sever its ties to the troubled Archegos family office. Japan's Nomura and Wall Street's Goldman Sachs were also forced to sell stocks on behalf of the highly leveraged Archegos.

If so, feel free to skip to the next section. Chia is one of the newest cryptocurrencies; it debuted in March of this year. It was founded by Bram Cohen, who also invented BitTorrent, and was designed to be a more energy-efficient crypto. It leverages the power of storage drives to farm crypto, rather than traditional GPU mining used by more mainstream cryptocurrencies like Bitcoin and Ethereum. It has a cap of 21 million total coins, the same amount as Bitcoin. Chia transactions are not yet enabled, so farming is currently the only way to acquire the currency. You will, of course, need at least some free storage space to mine Chia; the more, the better. These requirements should be easily met by any modern computer, so storage space will most likely be the only limiting factor in play for you.

At the edge of a lake on a fault line of the new Cold War stands a building that, depending on how you look at it, is either a relic of a failed revolution or the beating heart of a new one. In Soviet times, the Kuchurgan electricity plant powered a swath of the empire from Romania to Ukraine. Today, its red and white striped smokestacks still loom over the surrounding cornfields, making ants of the workers who file out at quitting time. Recently the station and its adjoining town—planned to Soviet perfection—has been a stop on the nostalgia tours that have boomed across eastern Europe off the back of the HBO series Chernobyl.
