1. Mineful's mining software is not asking the computers to do anything that they are not designed to. If the mining software is running during the day, there may be a noticeable increase in load, but this is understandable since the computer is being asked to work harder. Exorbitant usage can cause a computer to wear out quicker but our miner will not cause a new computer to significantly extend or shorten is life expectancy.
