In 2023, is it suitable to use miners to mine or buy coins?

In 2023, is it suitable to use miners to mine or buy coins? In recent years, with the increasing popularity of blockchain technology and the rapid development of digital currency, more and more people have joined the team of mining and buying of coins. In 2023, for most people, choosing to use a miner to mine or buy coins will be a critical decision. Advantages and disadvantages of miners High power consumption, high cost, and high technical requirements are the salient features of miners' mining. But at the same time, miners also have a stable income from mining and have the advantage of controlling the speed of block verification. Here are a few viable Bitcoin miners and their profitability in 2023. Antminer S19 Pro is a miner produced by Bitmain , which is very popular in the market. It is equipped with 114 BM1398 ASIC chips , which can achieve a faster and more stable mining experience. It is estimated that the average daily income of this type of miner in 2023 will exceed 120

Pool and Miner Setup

For the installation settings of Antminer T15, please refer to the Antminer T15 Manual on the Support-Asic Miner Manual page of the ZEUS MINING's official website.
After the setting is completed, the miner enters the high-performance mode, and the real-time status is displayed on the "Miner Status" page.

How to repair antminer T17 Hashboard and repair guide manual download

How to repair antminer T17 Hashboard and repair guide manual download This version contains the basic circuit schematic diagram and chip signal direction and voltage introduction We currently publish in Chinese and the English version will be released soon Basic overview: Antminer T17 single hash board uses a total of 30 hash chips, the model is "BM1397", and the signal direction is sequentially transmitted from U1 to U30. Signal direction: "CLK / CO / BO / RST", transferred from U1 to U30, "RI" is transferred from U30 to U1 It also passes 5 test points for testing and maintenance The five test points are: CLK-CO-RI-BO-RST (Please note: The location of the test points in different voltage domains are also different, please refer to the picture notes) For notes and instructions on the test points, please see the following articles: The whole board has 30 chips, divided into 10 voltage domains, and each voltage domain contains 3 chips For the description of

How to repair ASIC miner hash board

How to repair ASIC miner hash board Important parts of ASIC miners – Hash board One  ASIC miner consists of 3 to 5 Hash board, a control board, a casing, and software, among which the Hash board are easiest  to broken. because the ASIC bitcoin miner hash board consists of many serially connected ASIC chips. When they work, they will be in a high-temperature environment for a long time. In this environment, it is easy to burn the chip or scatter the solder due to high temperature which makes the hash board or the mining machine unable to work and no hash rate. How to quickly detective which chips broken it’s the most important when we repairing ASIC miners The Antminer chips fixture fast efficient and easy to use Bitmain Antminer repair inspection tool The ASIC bitcoin miner hash board consists of many serially connected ASIC chips.

How to test the voltage and ground value of the power supply unit of the Antminer S9 hash board?

How to test the voltage and ground value of the power supply unit of the Antminer S9 hash board? Antminer S9 hash board Antminer S9 hash board power supply unit Voltage and ground value test of Antminer S9 power supply unit 12V voltage test Test method: adjust the Fluke 15B+ multimeter to the DC gear; the red test lead is placed on the positive pole of the power interface of the hash board, and the black test lead is placed on the negative pole of the power interface. PIC chip voltage test There is a white dot next to the PIC chip, which is 1st Pin. Test method : Adjust the Fluke 15B+ multimeter to the DC gear, measure whether the 1st Pin of the PIC chip has output, and the normal voltage is about 3.3V. If there is no 3.3V, please check the connection status of the hash board test line to see if the hash board is normal; if not, you need to re-program the PIC. MOS tube voltage test There is a black dot on the MOS tube, which is the 1st Pin (Figure 1). This is because the voltage of t
