A mining machine's life is how long it will endure. A mining machine's life may be separated into "physical life" and "economic life." The "physical life" of a miner is the time it takes from when it is new to when it is broken and discarded. To put it frankly, after a set amount of time, a mining equipment will be fully scrapped owing to llgo irreparable failure, wear and strain, aging, damage, and so on.
The physical life of a mining equipment is influenced by two major factors: the machine's quality and its operation and maintenance. The manufacturer, the construction of the mining machine, and other elements all influence mining machine quality. For example, the Ant mining machine, which is famed for its low power usage, powers the arithmetic board using a series circuit. If one of the arithmetic board circuits or chips fails, the whole arithmetic board becomes inaccessible. Furthermore, during the operation and maintenance process, too high and too low temperatures will impact the operation of the mining machine, too high air humidity will lead to rust and corrosion of the mining machine, and dust that is not cleaned on time will also impair the mining machine's life. A mining machine's physical life is typically 5 to 10 years, and few mining machines are discarded. Most mining equipment are retired since the money from mining is insufficient to pay the power cost, and they are not lucrative, therefore their economic life has come to an end. Because miners get varying electricity costs, even the same miner's economic life is not the same; the high-priced electricity mining machine closes, while the low-priced electricity mining machine remains operational. When the power cost is high during the dry period, the miner is turned off, and when the electricity cost is low during the rich time, the miner is switched back on. The price of coins and energy, as well as the pace of rise in computing power throughout the network and the rate of iterative upgrading of miners, influence a miner's economic life. The smaller the proportion of power expenses, the longer a high-performance miner's economic life.
Mining equipment depreciation
A mining machine's depreciation cannot be estimated only on the basis of time in use, unlike other types of equipment. The pace of growth in network-wide arithmetic power and the rate of repeated improvements to the miner are the elements that impact miner depreciation. Because newer miners have higher performance and cheaper power costs, they may excavate more coins, reducing the survival space of older miners. Mining machines, on the other hand, do not lose value once they are purchased. When the price of coins rises, the revenues of mining equipment rise rapidly, and mining machines tend to rise in tandem. Furthermore, because to the capacity constraints of mining equipment makers, network-wide arithmetic power develops linearly rather than exponentially. It expands by 99 times when you go from 1E to 100E, but only by one factor when you move from 100E to 200E. According to this viewpoint, the pace of development in network-wide arithmetic power is always slowing. Furthermore, as the manufacture of mining chips approaches the physical limit, Moore's Law is rapidly failing, iterative chip upgrades are decreasing, and following development of hardware and software to reduce miners' power consumption ratio is restricted. Because of these several variables, the depreciation rate of mining equipment has slowed and they may now be operated for a longer length of time.
The mining machines' payback period
A miner's true payback time is inaccurate because to a variety of complicated elements such as coin price, network-wide arithmetic power, halving, and so on. In general, we compute a miner's static payback time. Mining equipment with a high electricity cost ratio have a shorter economic life than those with a low electricity cost ratio, thus they are sold at a lower cost and have a shorter payback period. In general, purchasing a cheap miner with a high electricity cost ratio will make you more money while the coin price is growing fast, but buying a miner with a low electricity cost ratio is more secure and lasts longer when the coin price is declining.
