ChainNode live broadcast room, revealing Avalon's most powerful mining machine A1166, is it a mining machine or a money printing machine?

Bitcoin computing power has reached 100E, and the dry season is coming. Will this be the moment when high-computing, low-power mining machines come on stage and old mining machines die on the battlefield? When Bitcoin enters the era of high-computing mining machines, will the mining business still make money?

On the evening of October 17, ChainNode live broadcast room welcomed guests such as Canaan Creative and Avalon Sales Director Chen Feng, Avalon After-sales Maintenance Center Director Chen Gongping, and Bibi News founder Xiaogui. Through off-site connection, they tested Avalon's latest A1166 and A1146 mining machines. The former has a rated computing power of 68T/S, a maximum computing power of 73T/S, and an energy consumption ratio of 46J/T, making it the most powerful Bitcoin mining machine in history. In addition, under the sharp attack of Jun Yao, the host of ChainNode live broadcast room, Chen Feng also revealed the payback period of the new mining machine and his industry observations on whether Bitcoin mining is profitable or not.

A1166 has a maximum computing power of 73.4T

Avalon A11 series Bitcoin mining machine is the latest Bitcoin mining machine released by Canaan Creative and has been mass-produced. Its previous generation of mining machines is A10 series, including Avalon 1047 with a rated computing power of 31T/S and a power consumption ratio of 58J/T, and Avalon 1066 with a rated computing power of 50T/S and a power consumption ratio of about 63J/S. The delivery time of the futures mining machines of both of them has been scheduled to mid-December. It can be seen that the market demand for Bitcoin mining machines is quite strong.

The A11 series is divided into two models. The A1166 has a rated computing power of 68T/S and an energy consumption ratio of 46J/T. The A1146 has a rated computing power of 56T/S and an energy consumption ratio of 57J/T. Compared with the A10 series, the computing power of the new mining machine that was launched a few months later has increased by about 36%, which fully demonstrates the power of Moore's Law. At present, the A1166 has also become one of the Bitcoin mining machines with the highest single-machine computing power on the market. A single-machine computing power of more than 60T/S has become the entry threshold for new-era mining machines.

Is the A11 series really that powerful? During the live broadcast, the ChainNode live broadcast room tested two mining machines through a connection. After more than an hour of operation, the measured data of A1166 was 68.8T/S, the power consumption was 46.3J/T, and the noise was about 75 decibels. The measured computing power of A1146 was 60.22T. Chen Feng introduced that they have measured the maximum computing power of the two mining machines to be 73.4T/S and 61.45T/S.

Four highlights, mining machines are more useful

According to Chen Feng, the A11 series mining machines have improved chip performance through chip architecture adjustments and reduced overall machine energy consumption through overall module optimization. In addition to strengthening basic functions, there are many detailed upgrades, which are divided into four parts.

First, the all-in-one design and spare parts simplify the trouble of purchasing additional power supplies and other accessories during the purchase of mining machines. And the fact that it can be operated by plugging in electricity and the Internet allows even novice users to mine easily.

Second, it supports network cable aggregation and adopts daisy-chain connection. After reducing the server ports, it can reduce the wiring cost of the mining farm and facilitate batch settings in the background.

Third, the 3300W adjustable power supply can protect the machine in case of power outage or voltage instability. When the price of the currency goes down, the machine can be operated at a lower frequency to reduce costs. The 4-fan configuration can provide strong heat dissipation.

Fourth, the main control module is implanted with multiple encryption algorithms and the Kanzhi K210 chip. The former can prevent the theft of computing power, and the latter can make the mining machine anti-virus.

A1166 has a static payback period of about 8.5 months and can be delivered in January 2020

According to the rated computing power, when the electricity fee is 0.36 yuan, currently (September 15), A1166 can mine 0.001314 bitcoins per day, with a daily income of about 77 yuan, electricity expenditure of 27 yuan, and a daily net profit of about 50 yuan.

Based on the official website price of 16,252 yuan, according to Chen Feng, its static payback period is about 8.5 months (calculated based on the current Bitcoin price). The A1146 is priced at 9,999 yuan, corresponding to a static payback period of about 7 months.

Chen Feng joked that the A11 series is not a PPT mining machine. It has been mass-produced as early as September. In the early stage, it was mainly for some old customers to experience it first. The official mass delivery time is January-February 2020. "The specific delivery time depends on the chip delivery time. Generally speaking, the whole machine can be produced 2 weeks after the chip is delivered. It can be foreseen that January next year will be a key node for large-scale delivery." He said that users in January will basically get the first batch of mass-produced machines.

Questions from live viewers

Are small miners exiting the market?

The threshold for mining is getting higher and higher, and institutional players are entering the market. They can purchase tens of thousands or even hundreds of thousands of mining machines in a batch. Even so, small and medium-sized miners with smaller demand still exist. They can also find electricity and places suitable for mining, and it is more convenient to move and transfer machines.

Will Bitcoin’s computing power see a surge?

Computing power and revenue are linked. Basically, there is a certain linkage between the surge in computing power and the rise in currency prices. If the price of Bitcoin remains the same, the computing power may decline in November, mining will enter a dry season, electricity prices will rise, and some old machines may withdraw from the market, thereby offsetting the computing power growth brought by new mining machines.

In the future, as large-computing-power mining machines are launched in batches, computing power will increase, but ultimately it should be linked to the rise in currency prices. Bitcoin is becoming more and more difficult to mine, and it is better to mine early than late.
