A well-maintained ASIC will typically last between 3 and 5 years, although it is not uncommon for it to last longer. If you're looking for a ballpark figure, you should assume that a GPU has at least 3 years of life. Even 10 years is not unheard of. The days when anyone could successfully mine cryptocurrencies at home on their PCs are long gone.
Whether you're mining Bitcoin, Litecoin, DASH, or a variety of other digital currencies, an Asic Miner is the most efficient method of mining crypto. Price - How much does the bitcoin miner cost? Cheap mining hardware will mine fewer bitcoins, so efficiency and electricity usage are important. Faster and more efficient mining hardware will cost more. Recently, ASICs have been released for Ethereum and large companies like Bitmain are constantly working on releasing faster and more efficient ASICs.
Canaan was one of the first companies to produce ASIC miners for commercial use, and over the years it has established a solid market presence and reputation for its expertise in the field of cryptocurrency mining. An ASIC can be 100 times more efficient than a GPU mining machine and the most popular cryptocurrencies have ASIC farms in a network. When ASICs came to market, the blockchain validation process was centralised, as more and more hashing power was consolidated into a handful of mining companies, rather than spread across many miners. This home Bitcoin miner is not only a good option for hobby miners, but also helps improve the decentralisation of Bitcoin mining as a whole.
Basically, regular people who can't afford to start a mining farm or source dozens of ASIC miners can partner with a company like CompassMining.
