[UPDATED] Choosing a graphics card for mining cryptocurrency in 2019

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.

AMD Radeon RX 5700XT and RX5700 graphics cards versus competitors in mining cryptocurrencies

RX5700XT_anounce_specification_mining_hashrateToday at E3 in Los Angeles on June 11, 2019, AMD held a full-fledged presentation of its new generation NAVI video card called the Radeon RX5700XT and RX5700. Compared with the first announcement at the end of May at Computex 2019, AMD has provided full technical specifications of its new video cards. Therefore, it will be interesting to compare the new products with competing products from the Nvidia company and AMD video cards of the previous generation and try to make a forecast of the performance of the Radeon RX5700XT and RX5700 in cryptocurrency mining

Best cloud mining contracts in the summer of 2019

cloud mining contractsOn many sites you can find reviews of various cloud mining services. However, there is quite a bit of information in the network about specific cloud mining contracts from various services and more about comparing them. In this material we tried to compare and analyze current offers from popular cloud mining services. In our comparison list there will be only time-tested quality services, as well as some newcomers who are rapidly gaining popularity. We have tried to exclude frank HYIPs from our list, which promise unrealistically high profitability. Unfortunately, comparing and analyzing cloud mining contracts is not an easy task. Firstly, all of them are quite technically different: they have different terms of life, ranging from 4 months to life, different prices for electricity (there are also contracts where electricity charges for the entire duration of the contract are already included in the price of the contract). Secondly, too many parameters can affect the calculations of the profitability of the contract, for example, the change in the price of a cryptocurrency and the complexity of its network. But we tried to bring all the contracts we considered to a common denominator and made up a summary table in which all technical aspects of contracts from various cloud mining services were indicated, and also tried to calculate the ROI (return of investments) and the estimated payback time of these contracts. In addition, at the end of the material you are waiting for some conclusions on this table, as well as some tips on choosing a contract.

Caution! Dirty bitcoin and what to do with it

bitcoin-dirtCryptocurrency 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 cryptocarrency stored. Any cryptocurrency that passes through such wallets is automatically blacklisted, and then all its movements are tracked as they blacklip more and more crypto wallets. Cryptocurrency stored on such wallets automatically becomes outlawed and at this moment the cost of such a “dirty” cryptocarrency 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.
