These two second-hand mining machines are suitable for mining in the city.

Bull market speculation, bear market mining, the currency circle has always said this, indeed, the profitability of buying coins is very difficult, and the mentality fluctuates greatly, and bitcoin mining mining is relatively a more stable investment. When it comes, the miners can sell the coins they have dug in the bear market, and they will get rich profits. In addition, the price of the mining machine will increase along with the bull market. If the new mining machine is purchased at the bull market, the input cost will increase. However, the batch of ant mining machines and Avalon mining machines that you bought in the bear market are appreciating.

However, many small white miners have some misunderstandings about the calculation of mining revenue. When they buy Bitcoin mining machines, they often estimate the future benefits based on the current mining difficulty, but they do not consider the difficulty of adjusting the mining difficulty. In fact, in the bull market to buy mining machines, miners not only need to invest in higher machine purchase costs, but also bear the risk of reducing the amount of coins that are dug due to the difficulty of mining. However, once the market begins to cool down, the mining revenue will be relatively lower due to the difficulty of mining and the decline in the price of the currency. At this time, the second-hand mining machine can easily be bought online. In order to let miners take less detours, the following RHY mine will introduce you to the most suitable second-hand mining machine purchased in 2019.

The following are the current second-hand mining machine models with good price/performance ratio in the mining machine market. The horizontal comparison and scoring are based on the price, power, power consumption, release time and ease of use of the mining machine.

Ant mining machine L3+

The ant mining machine L3+ was launched by Bitland in December 2016. It uses the LTE1 chip BM1485 developed by Bitland. The ant L3+ uses the Scrypt algorithm. Any Scrypt algorithm-based cryptocurrency can be mined by the Scrypt mining machine. There are currently no more than 100 cottage coins using Scrypt on the market. The shortcoming still needs to be overclocked, which can be steadily increased by more than 4%. Advantages: High cost performance, suitable for all the Scrypt algorithm of the altcoin, the heat is not bad.

PS: August 2019 is the time point for the production of Litecoin to be halved. It is speculated that there should be a wave of price increase after the halving period. It is recommended that you can now enter the market to dig Litecoin, and then switch to other Scrypt algorithms after reducing production. currency.

阿瓦隆矿机741.jpg

2. Avalon mining machine 741

Avalon Mining Machine 741 is a mining machine released by Jia Nan Zhi Zhi in April 2017. The initial price was about 10,000 yuan. The machine is made of 72 16-nanometer A3212V chips. The machine is made of aluminum casing. The power board and the double-layer heat sink are used for heat dissipation. The disadvantage is to use it with the Raspberry Pi. If you haven't used the Raspberry Pi, you can check the tutorial.

3. Ant mining machine S3

Ant mining machine S3 is one of the earliest released ASIC mining machine models in Bitland. Ant mining machine S3 uses ASIC hardware to optimize SHA256 algorithm. The machine consists of 32 28 nanometer chips, and the double violent fan enters and leaves the heat dissipation mode. The fan has a four-pin temperature-controlled speed adjustment, and the disadvantage is that the noise is very large.

4. Ant mining machine D3

The Ant Mining Machine D3 is the first ASIC mining machine released by Bitland using the X11 algorithm, which can dig the cryptocurrency of all X11 algorithms including Dash. The ant D3 was released in October 2017, and the price when it was on the line was 8500-10000 yuan. The disadvantage is that the overclocking operation should be carried out according to the physique of the mining machine. After overclocking, the calculation power can be increased by about 5-10%.

Current price: $43.3639

Calculation power: 19.3 GH/S

Power consumption: 1350W

Ease of use: 5 stars

Overall score: 4.5

5. Core moving machine T2

The core mining machine T2 is known as the terminator model of the bitcoin mining machine in 2018. The high-powered low-power machine has gradually become the first choice for miners. The core T2 uses a 10 nanometer chip process to achieve low power consumption. The energy consumption of TH is only 91.28J. The core T2 belongs to the integrated mining machine. The power supply has been installed on the top of the fuselage, which greatly saves the cost and reduces the space. The installation method is also very simple. Connecting the 6pin interface and connecting the Internet cable is OK. The downside is that the back end of the mining machine is in English, but it is also a very simple vocabulary.

Tips: Miners use the income calculator to check the profit of the mining machine before buying the mining machine.

Bitcoin prices are changing every second, and the difficulty of mining is constantly being adjusted. As a result, the benefits of mining can quickly turn from profit to loss. Of course, the low price of second-hand mining machines is not a weapon to maximize the profit of mining. It also needs to cooperate with low electricity costs. After all, the biggest cost of mining is the cost of electricity. At this time, miners need to choose a stable low-electricity mine for mining. For example, the RHY mine has an electricity tariff as low as 0.02746 US dollars per kWh, and 365 days a day, 24 hours a day mining mine. The operation services of the scale mines manage the risks from a professional perspective, helping the miners to win the bitcoin mining period.
