Check Mining Profitability Before Buying Mining Hardware

Before jumping onto the digital currency mining bandwagon and launching a small at-home mining operation, it is advisable to check mining profitability for the miner(s) you intend to buy and the coins you intend to mine. Digital asset prices change every second and mining difficulties adjust on an ongoing basis. Mining profitability can, therefore,  quickly move from profitable to unprofitable.

Hence, it is highly advisable to check mining profitability using specialized online mining calculators, such as the CryptoCompare calculator, before making any purchases.
