It takes a lot of time and energy to keep mining a particular coin. Digibyte, for example, costs about $120 per month to run. Your data center will most likely cost between $20,000-$30,000 dollars to set up. In addition, most cloud mining companies take a 30% cut from your profits whenever you sell out your hash rate (my current provider takes 15%). If you mine on the free market — as we do — these fees can add up quickly.
However, I believe there is still some money remaining in my account after I pay for running this server and buying all the hardware necessary to mine crypto so I’m not worried yet and am open to taking offers! 🙂
