Ironically the most profitable way to mine a coin is to not mine that coin all the time! Now this may sound a little crazy, but the reason for this is that the market and price of cryptocurrency changes on a per second basis. There are over 2000 coins in the market. Based on your hardware, the market price of the coin and the number of people mining that coin varies daily and often minutely on what is the most profitable coin to mine at any given time.
There are some really great single coin miners out there and some have better hashrates than others, but even with slightly higher hashrates they cant improve the cryptocurrency market and for this reason if you want the most profitable option you should use a multi coin miner like Cudo Miner. If we take Ethereum for example. If we just mined Ethereum and nothing else over the last few months, you would generally have been 10-50% worse off than using our multi miner depending on what hardware you have. That’s why we created a miner that you can still earn in your chosen coin and get a more profitable solution.
