The general rule is that Application-Specific Integrated Circuit (ASIC) miners are the best choice for crypto mining because they are specific to algorithms. They are algorithm-specific. ASIC miners aid miners in mining their preferred cryptocurrency with efficiency since they are specifically programmed for the specific cryptocurrency. For instance that a Bitcoin miner is designed to work with the SHA-256 algorithm while Zcash miner is optimized for the SHA-256 algorithm. Zcash miner is specifically programmed to work with an algorithm called the Equihash algorithm. In the same way, Ethereum ASIC miners are specifically designed for the algorithm called Ethash.

Furthermore that, in the event that an ASIC is made for a specific algorithm it is able to mine any cryptocurrency which follow the algorithm. So it is true that an Ethash ASIC miner is fine-tuned for the EThash algorithmand it is able to mine all the cryptocurrencies that adhere to this algorithm. For instance it is possible to use an Ethash miner is able to mine any cryptocurrency that follows an Ethash algorithm, such as Ubiq, Expanse, Etho, Ethereum Classic, Musicoin, EtherGem, Callisto, and QuarkChain.
