Canaan Technology Launches New Avalon A13 Series Bitcoin Miners

Canaan Technology Launches New Avalon A13 Series Bitcoin Miners According to the latest news, Canaan Technology announced the launch of the new Bitcoin miner Avalon Made A13 series, including Avalon A1346 and Avalon A1366. Canaan Technology said that the new generation of miners uses advanced ASIC technology, and the A13 series will include two different models. Compared with the 90 to 100TH/s hash rate offered by the A12 series, the A13 series has both hash rate, and energy efficiency has been enhanced. Canaan's CEO said the all-new A13 is a milestone in the company's over-computational energy consumption analysis. The model A1346 has a hash rate of 110 TH/s and an energy efficiency of 30J/TH. Model A1366 has a hash rate of 130TH/s and an energy efficiency of 25J/TH. Comparing the energy efficiency ratio of Bitmain's flagship S19 XP of 21.5 J/TH with that of Bitmain's M50S of 0.026j/Gh, the new series of A1346 is "very competitive" in terms of efficiency at

How long is the life of a miner?

How long is the life of a miner?

Participating in mining is one of the important ways to enter the blockchain industry and enjoy industry dividends. Moreover, mining is more stable and more suitable for large institutions and significant funds to enter the market than buying currency.
Mining is a highly specialized thing. Therefore, many new miners will face many problems before entering the market, such as: What are the ways to participate in mining? How to select miners scientifically? Is it more cost-effective to buy new miners or to buy used miners?
Today, we will solve a problem many new miners may encounter before entering the market: How long can the purchased miners dig coins? In other words, how long is the life span of miners?

1. The physical life of the miner

The life span of a miner can be divided into the "physical life" and "economic life". The physical life of a miner refers to the time from the time the miner is put into use in a brand new state until the miner is damaged and scrapped. Simply put, it is how long after the miner has used it, it will be scrapped entirely due to irreparable failure, wear, aging, damage, and other reasons.
Two main factors affect the physical life of miners: the quality of miners and operation and maintenance.
The quality of miners is closely related to factors such as miner manufacturers and miners' structural design. For example, the Antminer, known for its low power consumption, uses a series circuit for power supply. Therefore, if one of the hash board circuits or chips has a problem, the entire hash board will become unusable.
The level of operation and maintenance will also affect the physical life of miners. For example, the miner emits a lot of heat when running. If the miner does not dissipate heat in time or the fan on the miner is damaged, the continuous high temperature will cause the miner to shut down and even cause a short circuit inside the miner. In addition to temperature, there is also humidity. If the air is too humid, it may cause rust and corrosion of the mining machine. At the same time, we can use a dust removal fan to clean the fan ports of the miners regularly. Failure to clean the dust in time will also affect the physical life of the miners.
Under normal circumstances, the physical life of miners can reach 5-10 years. For miners, they are more concerned about the economic life of miners.

2. The economic life of miners

The economic life of a miner refers to the useful life of the miner from the perspective of cost and profit. To put it simply, look at the two indicators of miners' electricity expenditure and mining output.
When the mining output of the miner cannot cover the electricity bill, the economic life of the miner ends. Under normal circumstances, the economic life of the latest miners can reach more than three years.

The mining output of the miner is greater than the electricity expenditure, and the miner can always run

The mining output of miners can be divided into block rewards and handling fee rewards. Taking Bitcoin as an example, suppose that the block reward is 12.5 BTC and the handling fee is about 1.4% of the block reward. The Bitcoin network is prone to congestion during the bull market, and the handling fee will increase. For example, at the bull market's peak in 2017, a single block The commission reward is as high as 10BTC or more.
The mining competition is fierce. The sum of the daily mining output of all miners is determined. The higher the hash rate involved in mining, the lower the output per unit hash rate.
Taking Bitcoin's entire network hash rate of about 109EH/s as an example, based on the average daily output of 1800 BTC, the daily income per TH/s unit hash rate is about 0.00001624 BTC. If you have a hash rate of 55TH/s (for example, an Antminer T17), your daily mining output is about 0.000891 BTC.
The output of hash rate per TH/s is inversely proportional to the hash rate of the entire network. If the hash rate of the entire network increases, the output per TH/s hash rate will decrease. Generally speaking, the hash rate of the entire network rises quickly in a bull market, and it rises slowly in a bear market and may even stagnate or fall.
In addition, in the long run, miners are iteratively upgraded, and the performance of new miners continues to improve. In this process, old miners with low performance are gradually eliminated. The hash rate of old miners is a cushion for new miners, and the exit of old miners slows down the whole process. Therefore, the increase in network hash rate can appropriately extend the economic life of new miners.

Low electricity costs extend the economic life of miners

The cost of electricity has a more significant impact on the economic life of miners.
The electricity used by the mine is mainly thermal power and hydropower. The price of thermal power is relatively stable in places where thermal power is concentrated; during periods of high water supply, electricity is cheap, and during dry periods, electricity is expensive.
During the period of water wilting, some miners shut down the miners and kept them sealed. When the water source is full, the miners will restart the miners if mining can continue to make profits.
Different miners have different electricity costs, and electricity costs are also the core competitiveness of miners. Therefore, the economic life span of the same miner is also different. For example, because of the low currency price, many small miners had to shut down the Antminer S9 because of the high electricity costs. Or sell miners to big miners who have an advantage in electricity rates.
At present, some miners are also shipping the miners that will be eliminated, such as T9+, to the Middle East and other countries with lower electricity bills.

Bitcoin halving every four years has an essential impact on the economic life of miners

Due to the block reward halving mechanism, Bitcoin's block reward will be halved approximately every four years.
After the Bitcoin halving is the first to bear the miners' brunt, because the miners' mining output will be directly reduced by half (regardless of the fee reward), some old miners with low performance will face the fate of shutdown and elimination.

Advances in technology make the economic life of miners longer and longer

The current mainstream miner chips are 7nm and 5nm. However, as the miners' chip manufacturing process gets closer and closer to the physical limit, Moore's Law gradually fails, and it becomes more and more challenging to upgrade the chip.
The iteration of the chip is gradually slowing down, and subsequent software and hardware upgrades have a limited increase in the power consumption ratio of miners, which may extend the economic life of existing miners.

3. Summary

The life span of a miner is divided into the physical life span and the economic life span of the miner. As a miner, we need to pay attention to the economic life span. The main factors that determine the economic life are the miner’s electricity expenditure and mining output. When the electricity expenditure exceeds the mining output, the miner’s economic life expires.
