Economies all over the world are suffering from the effects of the COVID-19 coronavirus global pandemic; even digital currencies have been impacted by the disease. September 9, 2020 was the last time Bitcoin (BTC) traded below $10,000 despite the news that four of BitMex’s executives were being indicted October 1, 2020. This shows great optimism for the future, and perhaps even a bull run for BTC that could be happening soon.
“It’s bullish to see that Bitcoin trading infrastructure is so strong given that the former largest bitcoin derivatives trading platform can lose 25% of [its] open interest deposits overnight and the markets just shrug it off” said Daniel Koehler, liquidity manager at cryptocurrency exchange OKCoin.
Even with an immediate drop in Bitcoin due to President Trump’s tweet rejecting another stimulus check for COVID-19 relief, the overall price did not drop below $10,000. With this steady rate continuing, now is a great time to invest and mine as we may see a spike in Bitcoin prices sooner rather than later. While finding Bitmain miners are scarce these days due to the feud between co-founders Jihan Wu and Micree Zhan in which 10,000 Antminers went missing, Wattum still has new opportunities for Bitcoin miners.
Visit our store to invest in mining equipment while the BTC market holds steady. Limited quantities of Antminers S17+ and Pro’s are still available in the United States. Wattum is also accepting pre-orders now for the S19, S19 Pro, and more.
Bitmain has dominated the ASIC market for years, making alternative manufacturers almost irrelevant. However, with the recent power struggle between Bitmain’s founders, and improved miners being manufactured by other companies, more offers are beginning to become more attractive.
Wattum recently received a batch of Whatsminer M30s from MicroBT. After several tests, we are excited to share our review. First and foremost, here is what the miner looked like upon arrival:
With the amount of devices we have to disassemble, repair, air-blow, and more every day, we were pleasantly surprised that there were no defects or problems with the miners. After testing the devices, we decided to disassemble them to see how the inside was arranged. Fortunately, the devices were not sealed, giving us the ability to look at all of the components in detail.
When first looking at the miner, we could see the typical layout consisting of a cooling system, power supplies, and the main unit hashboards. Before moving any further we decided to go on MicroBT’s official website. Here we were able to find full instructions on disassembly and assembly of the M30s.
Since Bitmain’s 9th series, the company has had several difficulties with radiator solutions. The Whatminer M30s, in contrast, has one-piece radiators with thermal breaks and thermal paste, eliminating this issue.
Online Board Status
A great way to see the status of the online board is through the slots. The indicators on each blade can be seen easily without even having to connect through a web-interface.
MicroBT released its own solution for complex maintenance of its devices – WhatsminerTool. You can easily download it from their website. This program is similar to BTC Tools, but it’s customized for Whatsminer.
Our first impressions of the program were very positive. It had a sleek design that was easy to use. Conveniently, the software provides all of the error codes, eliminating the need to look into logs. There are several datasheets on them, along with a table of error codes containing possible solutions to issues.
In addition to the usual hashrate data for each individual hashboard, there was also pool data and error information on the miner statistics page.
There were also performance profiles in the web interface. The default is Normal, but you can also select Low or High.
This solution allows you to search for devices in the network in a given range, and apply various settings at once to a group of devices. Some examples are changing the pool, workers, and other parameters.
Like all other ASICs, overheating can be a major issue depending on the environment. The miner’s temperature is displayed in the logs, and if too hot it will automatically shut down. With the Bitmain 17 series and M30s all in one room, we found that the M30s maintained a stable temperature, while the nearby Bitmains overheated heavily, and generally had a noticeably large temperature variation depending on the time of day.
When comparing the M30s equipment to Bitman, the WhatsMiner’s hardware components were superior.
Typically each batch of Bitmain we tested in the past had a high percentage of units with non-functioning hashboards, even those that came under warranty. WhatsMiner, on the other hand, provided much better reliability results. Our first batch statistics were 40 out of 40 working units. Though, we still need to test that the quality does not deteriorate over time, as this often happens.
Of course the most important aspect of any miner is its performance. With 40 devices at our disposal, we found the following results:
Average consumption – 3550W Average hash rate (on the High profile) – 94.25TH Average efficiency indicator – 37.66J/TH
Maximum hash rate – 96.05TH At the same time, the consumption was – 3627W Minimum hash rate – 92.9TH At the same time the consumption was – 3504W Best performance demonstration – 37.03J/TH
Overall the M30s miners from MicroBT made a great impression. We would highly recommend them, as they did not cause any problems during usage, and had an extremely low reject rate compared to the popular 17 series from Bitmain. In the future we hope to get newer models from this company, after which we will prepare another overview.
When it comes to mining for cryptocurrencies, it’s common knowledge that a miner’s investment in equipment directly relates to their profitability. This is why we’re introducing the new generation of Bitmain ASICs, the Antminer S19, which is more reliable, efficient and profitable than previous editions. A vast improvement on its predecessor, the S17, the manufacturer has listened to user feedback and made the following changes to the latest iteration of the product:
Radiator System Redesign
One of the biggest user complaints with the S17 Antminer referred to the inefficient way the radiator operated when the device was overheating which often dumped heat directly onto the chips in some instances. The S19 solved this problem by replacing the several small radiators with a larger, more powerful singular radiator and physically attaching them to the device more securely with screws. The only con that can be seen with the new design is that they only attached the larger radiator to one side of the device as shown in the below image.
Thermal Interface Redesign
The second most encountered issue with the S17 was related to the thermal interface adhesive. At high temperatures, the TIM glue that was being used began to deteriorate and lose its original thermal transfer properties. Bitmain has fixed this completely in the S19 model, which now features a TIM paste on the chip side. This change single-handedly increased the thermal transfer between the chips and the fan making the average operating temperature of the S19 clock in at an optimal 77-78 degrees fahrenheit in an optimized room.
Power Supply Redesign
The third most common user complaint about the S17 was the failure of the power supply to the device; and while Bitmain repeatedly addressed this issue under warranty, the process was very time consuming. The new S19 edition device features a PSU APW12 v1.2 INPUT 200-240V 10A X2 C13 that will not start the fan if just a single power cable is connected, a great improvement over the last edition.
Firmware Dashboard Redesign
A welcome change to the latest Antminer miner was a completely overhauled firmware redesign for the S19 model; a common complaint being that previous interfaces looked very outdated and unprofessional. This modern and simplistic dashboard allows users to track the key metrics they need to closely monitor their hardware in order to maximize profit margins and efficiency.
Increase in Overall Profit Margins
Of course the biggest driving factor for the creation of the S19 model is obviously to put more crypto in the wallets of their users. The S19 outperformed the S17 at a two to one ratio, with the new specifications of 95TH +-3% 2500W 34J\TH.
In terms of profit, the S19 earns approximately 30% more than its predecessor at the current yield and cost of $0.05 per kw. Keep in mind, however, that the prices and returns, like the market, are constantly fluctuating.
The design changes and vast performance improvements to the Antminer S19 over the S17 show that Bitmain is at the forefront of Bitcoin mining technology. The new Antminer firmware and changes in device design and structure over the previous model will ensure a much more reliable and durable device over time. From doubling product performance to the 30% increase in average profitability, the next generation of crypto miners by Bitmain are made to continually improve the mining income of its users.
