Thinking of using it to mine Bitcoin? Despite an increase in popularity over recent months amongst botnet operators, malware-powered Bitcoin mining brings little to no financial return, say experts. Unfortunately for the cybercrooks, however, it seems that a botnet-turned-mining rig doesn’t actually make much money in real life. According to researcher estimates, a botnet controller attempting to mine Bitcoin with a 10,000 system network would initially see a net loss in operations and with increasing difficulty cycles productivity would plateau off without turning much of a profit. That rate becomes even lower when mobile devices are added to the equation. Researchers note that with less powerful processors and limited battery life, mobile devices are ill-equipped to function as dedicated cryptocurrency mining tools, especially when this is done via covert malware infections.
