Since the beginning of November, the price of Bitcoin has fallen by more than 46%, and the network hashrate by 30%. The BitMEX analytics department Bitmain Antminer S9 ASIC miners and about 1 million other devices were disconnected from the network. Many understand that the cryptocurrency market is in a real crisis, and the mining industry is experiencing not only strong pressure, but also the patience of miners.
In this review, we will tell you which ASIC miners have lost their profitability and stopped bringing profit to their owners. We will not go through hundreds of devices on the market, but only those that were profitable before the recent collapse in the price of Bitcoin.
Technical characteristics of WhatsMiner M3X
Hash algorithm: SHA-256 (suitable for mining Bitcoin (BTC), Peercoin (PPC), eMark (DEM) and other cryptocurrencies.); Chips: 198 * SMiT1700 28nm ASIC Hashrate: 12-13TH/s Power consumption: 0.17 kW/th Power block: what Power P3, 2100 W, 93% efficiency Controller: included Operating temperature: -5C ~ 40C Size: 335 mm * 125mm*155mm Weight: 6.1kg
General characteristics M3X is an improved version of the M3 miner. This interesting new product is focused on Bitcoin mining and produces from 12 to 13 Terrahash per second. The first thing that catches your eye when visually examining the Pangolin Whatsminer M3X is its compactness, especially when you compare its dimensions with such a “hulk” as the Antminer S9.
An interesting feature of the Whatsminer M3X ASIC miner is its 28-nanometer chips, which, in turn, affects the level of power consumption of the device. It should also be taken into account that during operation the device can become quite hot. Precautions when handling ASIC
The service life of equipment depends not least on its correct operation and handling. When connecting the 6-pin connectors to the hashing board, you must ensure that the correct position of the wire is maintained. A special video on the website www.pangolinminer.com will help you make sure that you have connected the 6-pin connectors correctly.
After connecting the specified cables, you should connect the 3-pin and 6-pin wires to the control board, as well as the Ethernet cable. Only after these steps can the user connect the power, thus starting the miner in automatic mode. During the operation of Whatsminer M3X, it is recommended to keep the wires away from the place where the air exits the ASIC.
If the user needs to move the miner from one place to another, he should take the device by the body (at the same time taking the power supply), and not drag the device by the wires. The cable between the control and hashing boards also cannot be used as a handle when carrying the device. Otherwise, the device will be damaged.
Important! After connecting the power, it is strictly not recommended to move the wires: this may damage the hashing board.
The M3X ASIC miner is a good option for Bitcoin lovers. The high performance of the device is ensured by an impressive hashrate; in addition, this model features optimized power consumption. And the compact dimensions of the device will allow the user to conveniently place it indoors.
How to buy WhatsMiner M3X?
You can buy the WhatsMiner M3X miner either from stock in China or by pre-order from the factory.
Manual and firmware update for ASIC WHATSMINER M3 M3X via local network
Last updated on 08/26/2021
Introduction.
Pangolinminer regularly updates its firmware to improve mining speed. There is even firmware that reduces power consumption. ASICs work differently with each firmware version. For example, M3X mines faster with newer firmware, and M3 can mine better with both new and old. The firmware version that suits you for the most efficient mining can only be selected by installing all the firmware. You need to try everything, but if you are satisfied with your speed, you don’t have to experiment.
Firmware update is carried out using the program:
WhatsMinerTool_User_Guide&Software —
It works in WINDOWS 7/8/10
You can also use this program to configure workers and passwords for pools. Moreover, this can be done en masse, i.e. if you have 20 ASICs, you can update the firmware for all of them at once or change the pool settings for all 20 of them at the same time.
Main window of the program.

- ② global control buttons for all tabs.
- ③ tabs you can select to perform the operation.
- ④ options and control buttons for a specific tab.

IP Search.
- Here you set the Whatsminera IP search range. Whatsminer's IP range can be from 192.168.1.1 to 192.168.255. The picture shows the range 192.168.1.1 to 192.168.20.

Import IP addresses.
You can also import your miner IP address from a text file by clicking the button. IP address text file format: one IP address per line. As below:
192.168.1.1192.168.1.2192.168.1.3
You can create the import file yourself or download it below and edit it in accordance with the IP of your ASICs

You can also remove IP from the list:
Export IP:
You can also save your edited IP list:
Restart CGminer of all ASICs in the list:
Reboot all ASICs in the list:
IP ASIC Definition
After you have set the IP range, click start and the program will poll the entire specified IP range; if the program has found all the IPs of your ASICs, there is no point in searching further, click STOP.
Automatic detection of IP ASIC MINER:
After running IP detection, WhatsMinerTool will automatically detect and capture the miner's IP address. You can report the miner's IP address as follows: Press the long key of the control board (next to the SD card slot) for about 3 seconds, when you see the red and green LEDs flash about 3 times, then the miner has reported its IP address. successfully. And at the same time, WhatsMinerTool will receive the specified IP address, for example:

TOP 5 unprofitable ASIC miners for Bitcoin
Outdated ASICs such as Bitmain Antminer S3, S5, S7 are not worth considering at all. They mined to zero when Bitcoin was still trading at $6,200, and now even a free socket will not save you. As for Bitmain Antminer T9 and T9+, they are also unprofitable and are only suitable for heating a living space.
AntMiner S3 from Bitmain
MicroBT Whatsminer M3X . This ASIC was introduced in March 2022 and was designed for a payback of 11-12 months. Already in November, M3 began to mine at zero, and now it is completely minus. This is also probably one of the strangest devices on the market: just imagine - delivering 12Th/s with a power consumption of 2000 W.
MicroBT Whatsminer M3X
Pantech WX6 . A fairly powerful device that produced 34Th/s with an unrealistic power consumption of 5000 W. Since November 20th, WX6 began to mine in the negative. Now on message boards they are asking for 30,000 rubles for it, but in fact its price is a maximum of 1,000 rubles (exclusively for experiments with firmware).
Pantech WX6
Canaan AvalonMiner 741 . Now many distributors sell it at cost - $133. This budget device produced a modest 7.3Th/s with a power consumption of 1150 W. You can only buy it if you have access to a free outlet. The income will be $27 per month and will pay off in 5 months. In other cases, it is unprofitable.

Ebang Ebit E9.2 . This ASIC produces 12Th/s with a consumption of 1320 W and at a Bitcoin price of $3500 it can still generate $47 taking into account electricity costs. But if we take the marked minimum of Bitcoin at $3200, then Ebit E9.2 mines to zero. Moreover, distributors are asking $2,136 for it, which is unthinkable given such profitability.
Ebang Ebit E9.2
Bitmain Antminer V9 . A very controversial device released in March 2022 and which was often called the starting point for low-cost mining. V9 produced 4Th/s with a power consumption of 1027 W, but the fall in the price of Bitcoin from $6200 to $3200 made itself felt - profitability of $0.30 per day with a free outlet. The V9 is currently asking $188, but only a madman would consider buying it.

Unprofitable ASIC miners for other cryptocurrencies
PandaMiner B5 Plus for Ethereum mining . The device was introduced in February 2022 and was designed for an annual payback. Its hashrate was 110 Mh/s, and consumption was 800 W. After the ETH price fell, ASIC began mining at a minus rate, which it continues to do successfully to this day.
PandaMiner B5 Plus
Dayun Zig D1 for DASH mining . Complete chaos. The first delivery of ASICs was made at the beginning of November 2018 and a month later Zig D1 lost all profitability. Profitability has decreased almost daily and now the ASIC miner is operating in the red.
Dayun Zig D1
iBeLink DM56G for DASH mining . This industrial giant produced 56 Gh/s with an energy consumption of 2100 W and was able to produce $300 per month. After December 6th it went into negative territory and remains there to this day.
