Mining crypto currency on laptop (notebook computer)

To get a crypto currency, there are two ways: buying and mining, and mining crypto currency is the simplest and safest way. for mining, you can use any programmable computing device, starting from mobile phones and ending with specialized devices for mining by Asic. Recently, we have already discussed the mining of crypto currency on mobile phones, today we will focus on more powerful devices - laptops. Further, we will evaluate their performance in mining, calculate the yield and make a final conclusion on the use of laptops in the mining of crypto currency.

Mining on a mobile phone (smartphone)

Now everyone in their hands now has a smartphone, which  is comparable to full-fledged computers 5-10 years ago. Therefore, many reasonably raises the question of the appropriateness of using smartphones for the mining of cryptowl and bitcoin in particular. In this article, we will try to answer this question and discuss in detail the topic of mining on mobile devices.

Asic Miner Spondoolies tech SPx36 - 540GH/s on algorithm X11

If you have been watching the mining crypto currency for a long time, you probably heard in 2014 about a successful model of the SP 20 miner from the Israeli company Spondoolies tech. Since 2016 this company has left the open market of the asic miners and we have already forgotten about it up to this point. As it turned out, the company still exists and is working on a new asic miner for the X11 mining algorithm called Spondoolies Tech SPx36. The dimensions and power consumption of this asic are calculated for installation in server racks in data centers, so the new product is most focused on the corporate sales sector.

Mining on GPU - detailed guide for beginners

Now, when the crypto currency is so popular that it is said everywhere: on the Internet, on TV and in other media, new information sites and Youtube channels, various analytical resources and services are constantly appearing, the number of online crypto-exchange exchanges is growing by leaps and bounds. Even governments of different countries are constantly discussing the phenomenon of crypto-currencies and block-technologies, trying to legalize the crypto currency and bring it under the legislative framework, or vice versa, considering Bitcoin a direct threat to the established banking financial system. Today the issue of mining of crypto-currencies (mining) is discussed rather widely, as one of the most interesting topics for ordinary users. Many have probably heard that Bitcoin, as well as another crypto currency, can be extracted as such, but the technical subtleties and how to start doing the crypto currency mining, what this might require and how to do it all do not know. In this material, we will try to explain in as much detail and simple as possible how the average user starts to earn crypto currency from scratch, what kind of crypto currency and on what devices it is profitable to mine in 2018, how to collect a simple mining of the farm, what equipment is best suited for this at the moment, what programs Use for extraction, where to store and how to withdraw the extracted coins.

The new motherboard for mining AsRock X370 Pro BTC+

AsRock is well known as the manufacturer of the most popular motherboards for the crypto currency. Once upon a time this company created the trend of "miner's motherboards", the release of its first model AsRock H81 Pro BTC. Since then, many companies manufacturing motherboards have followed in the footsteps of AsRock and supported this trend with their motherboard models. And today we have a choice of such models for mining for every taste and purse. While the novelty AsRock X370 Pro BTC + is not as revolutionary as its predecessor, it still brings a number of new opportunities for miners, in the form of the ability to install new APUs from AMD. Typically, processors costing about $ 100 do not support enough PCIe lines to work with a large number of video cards simultaneously, although this motherboard with a new AM4 connector can change this, due to compatibility with forthcoming inexpensive Rizen processors that will support 28 PCIe lines.

Canaan Avalon miner 851 - 15Th/s on 16nm tech process

The well-known company for the production of the asics Canaan has introduced a new model Avalon Miner 851 already available for sale. The novelty is an improved version of the long-known Asik Miner Avalon 841 and is built on the basis of the same 16nm process technology. Therefore, there is no need to expect any breakthrough in energy efficiency from the 851 model, and even on the contrary, the hashed increased from 13.5Th / s to 15Th / s has led to a decrease in energy efficiency from 0.099J / TH to 0.11J / TH. From which we can conclude that the Canaan Avalon miner 851 is an overclocked version of the previous model 841.

Goldcard - new hardware wallet for crypto-carrency Bitcoin

The company Coinkite known for its product Opendime USB bitcoin Stick, on the same principle decided to make a cheap, secure open-source hardware wallet Coldcard cost of pre-order at 69.99USD. The hardware wallet has a display and a full keyboard and microSD for offline use. To successfully simplify the work with the wallet, developers abandoned the specialized software on computers.

Bitmain Antminer S9 Hydro - 18TH/s with water cooling

Releasing "novelties" S9i and S9j Bitmain is trying to squeeze the maximum out of rapidly aging chips at 16nm process technology. And apparently this is not very good for them, because the other day we saw another "novelty" on the same chips chips - Bitmain Antminer S9 Hydro at 18 TH / s. As you can guess from the title, the new S9 incarnation this time offers a new liquid cooling system, plus an increased 4TH / s hash due to the increased overclocking of the asics chips.

Liquid cooling is several times more efficient than the air cooling used before, so the developers managed to show a new hash record by increasing the power consumption from 1350W to 1728W, while the operating temperature became even lower than that of its "air" brothers.

Mining CryptoCurrency CPU VS GPU

After the hot 2017, when probably half of the world's population was engaged in mining, there was quite expected cooling of the market. Because of what the profitability of mining activity fell to the payback of equipment to the minimum values ​​of 2-3 years. And this is already taking into account the fall in prices for ashik several times and on video cards by 20-30% from their maximum value in the period of increased demand. At this not the most favorable moment, AMD makes a discount of up to 50% on its HEDT Ryzen Threadripper processors of the first generation, which, as we know, show themselves well in the mining on the algorithm of Cryptonight and its clones Cryptonightv7 and CryptonightHeavy. Such a serious drop in prices for top-end CPUs interested us in how quickly to pay off Ryzen Treadripper in the current conditions of mining crypto-currency and compare this indicator with video cards.
