  • halving bitcoin 2020On May 12, 2020, a significant event will occur in the cryptocurrency industry - halving the bitcoin or reducing the reward for mining the first cryptocurrency in two to 6.25 BTC per block. This will be the third halving in the history of bitcoin: the first occurred in October 2012, when the reward for miners fell from 50 BTC to 25 BTC, the second halving occurred in July 2016 with a decrease in reward to 12.5 BTC per block. Many enthusiasts, investors and miners believe that these two events were the catalysts for the sharp increase in the value of the Bitcoin cryptocurrency in 2013 and 2017. After another halving in May 2020, a significant change in the value of Bitcoin is also prophesied, but we do not completely agree with such statements, and then we will try to explain why you should not wait for Bitcoin to rise in price by 50% or more percent from the current values ​​only because of halving.

  • The current videocards hashrate In 2020, as before, new cryptocurrencies with "revolutionary" mining algorithms for the GPU continue to enter the market, but like in previous years, the leader remains the Ethereum cryptocurrency mining algorithm - Dagger Hashimoto or simply ETHash. Mining algorithms based on Equihash, MTP, RandomX are also very popular. Of the new algorithms that have appeared over the past year and have gained popularity, it is worth noting variations of Cuckoo, BeamHash and ProgPow. These are the cryptocurrencies GRIN, MWC, SWAP, Beam, Sero, BCI. The remaining new and revolutionary cryptocurrencies could not interest miners in the long term.

  • mining pool choiceMining Pool  - a specialized service for miners, which combines hundreds or thousands of mining computers into one. Small and medium miners are added to the pools, whose capacity is not enough to find at least one or two blocks per day, i.e. with the help of the pool, miners receive a stable daily income, thus eliminating the element of luck, which may not be on your side for several months. Those. If your hashrate does not allow finding on average at least one block in 1-2 days, then it is better to pay a small commission to the mining pool and receive a reward for mining stably according to calculations. For popular cryptocurrencies Bitcoin, Ethereum, even large miners with equipment worth millions of dollars use the pool, because the number of participants is so large that even such large miners prefer to pay 1-2% of the commission than to maintain equipment for a week, pay for electricity and wages and, in the end, get nothing in return just because the probability theory was on the other side . If we have already figured out why to use the mining pool, then we will talk in more detail about how to choose it correctly.

  • cloudmining_scamCloud mining services became widespread in 2017, when there was a booming demand for video cards, ASICs and other mining equipment against the background of a sharp increase in the value of cryptocurrencies. In addition to accessibility, cloud mining services from investors remove other problems related to the purchase and maintenance of mining equipment. That is precisely why these services have become popular, and  in popularity, money and rush demand there scammers always appear. As you can easily guess, the cloud mining industry simply drowned out a wave of hype cloud mining projects or simply pyramids under the guise of cloud mining, especially since it’s as easy as tricking a trusting layman who is not versed in cryptocurrencies. At the peak of popularity, it came to the point that among all this numerous variety of “cloud mining” it was almost impossible to find really working projects. Now in 2020, when Bitcoin from 20,000USD fell to 3,000 USD, all such hypes ceased to be paid, but did not cease to exist. Many sites of such scam services continue to work, and on a new wave of interest in cryptocurrencies, they can again actively begin their advertising activities to attract money from gullible investors.

  • btc_price_mining_2019If the value of the first Bitcoin cryptocurrency is monitored almost daily by all crypto enthusiasts, then not everyone knows the cost of its extraction. Moreover, this parameter is also important not only for miners, but also for investors, because it can affect the final value of Bitcoin itself. The cost of mining bitcoins depends on many factors: the effectiveness of the equipment, its cost, the cost of electricity, the complexity or hashrate of the network. And each of these parameters has a strong influence on the final payback result of Bitcoin mining.

  • motherboard_mining_2019When assembling GPU mining rigs, the selection of components is important for reliable and stable operation of the entire system under increased load during mining 24/7. Motherboard -one of these main components that require special attention when choosing. On which the number of installed video cards, the amount of memory, the processor and the overall stability of the entire system will depend. In addition, mining motherboards must withstand increased current loads so that the power paths on the board itself do not burn out. In order to simplify the choice for miners of components for their GPU rigs, manufacturers began to produce motherboard models specifically designed for mining, i.e. under the requirements of highly loaded systems, plus the possibility of connecting a large number of GPUs is provided

  • asic_vs_gpu_choosingDuring the Spring - Summer of 2019, everyone can observe an intensive recovery of the cryptocurrency market, and along with the rising cost of crypto assets, the interest in mining cryptocurrency is growing. Therefore, many novice miners are increasingly beginning to wonder: "Where to start?". If we consider classic POW (Proof-of-Work) mining, then today the main tool for POW mining is video cards and Asic devices, since CPU mining is of little relevance and expedient  only for botnet networks, and FPGA miners are extremely expensive and practically inaccessible to the average customer. Therefore, all who are going to engage in mining cryptocurrency stop on the choice of these two options - Asic or video card. And this choice is not as simple as it may seem at first glance, and will depend on many factors, which we will try to make out below. Also at the end we will consider the payback factor of equipment, which many mistakenly put in the first place in the choice of mining hardware.

  • proof-of-stake_staking_miningThe basis of the work of the blockchain technology is distributed P2P networks with a protection mechanism against recording incorrect data by assigning a "weight" to each participant of this network. Today, there are two main models of weight assignment: POW-performance of work or all the usual mining cryptocurrency, POS - share ownership of cryptocurrency. And over time, the share of projects choosing the POS model is constantly growing, reaching as of June 2019 an 8% share of the capitalization of the entire crypto market. The long-expected transition from POW to POS Ethereum, the second most popular cryptocurrency, in early 2020 will raise the capitalization of POS currencies to 20%, which will be a turning point in the transition of the entire industry to a less expensive method of keeping the blockchain up to date. Global changes in the near future will affect the mining industry on the CPU, GPU, FPGA and ASIC, because The relevance of POW mining will fall, as the result of competition among miners and among mining pools will increase dramatically, which will lead to even greater squeezing of small participants from the market. In the era of POS mining, on the contrary, such a phenomenon as Staking will emerge that will replace the mining pools from the current POW mining era.

  • Choosing a graphics card for mining cryptocurrency in 2019We continue our annual analysis on the market of video cards and their use in mining cryptocurrency for 2019. Compared with the previous analysis at the beginning of 2018, the cryptocurrency market has undergone strong changes associated primarily with a decline in cryptocurrency prices to 90% from last year’s values. Against this negative background, specialized ASIC and FPGA devices form an increasing competition in the mining of cryptocurrency to video cards, which further worsens the situation for the owners of mining farms on video cards. The release of a new generation of Nvidia video cards at the end of 2018 had virtually no effect on the alignment in choosing the best video card for mining. we did not see a sharp decline in prices for video cards of the last generation of the GTX10xx series, moreover prices for video cards continue to remain higher than they were before the mining boom in 2017-2018. Despite this, the mining on video cards in 2019 continues to be relevant, but already at the expense of the used video cards market and new asicresistant mining algorithms. These arguments were in February, when the cost of cryptocurrency was at the bottom. Now in June 2019, the year when the cryptocurrency went up by 2-3 times and new video cards came out, we completely recalculated the payback of the GPU in the mining at the moment.

  • bitcoin dirt, aml check, black crypto listCryptocurrency based on blockchain technology, including Bitcoin, has many advantages. It is an independent method of transferring value with low commissions and fast transactions independent of any government, while cryptocurrency is easy to share to millionths without losing its value. All these statements were true until the cryptocurrency did not become so popular that in some countries it became recognized as legal tender or electronic asset. From this point on, due to the blockchain's openness of some cryptocurrencies (Bitcoin, Ethereum, Ripple and others), black lists of crypto wallet began to appear on which stolen cryptocurrency stored. Any cryptocurrency that passes through such wallets is automatically blacklisted, and then all its movements are tracked as they black list more and more crypto wallets. Cryptocurrency stored on such wallets automatically becomes outlawed and at this moment the cost of such a “dirty” cryptocurrency starts to fall sharply, because buying and cashing a dirty bitcoin or ethereum in your own name of  will automatically make you at least a witness of a theft or worse yet an accomplice in a crime.
