It Takes fourteen Million Android Phones to Earn One Bitcoin

Bitcoin, Dogecoins, and other cryptocurrencies have grabbed a lot of headlines for their explosive growth (and bust, and growth, and, well…). The trick is that generating this currency—”mining” it—requires an awful lot of computing power. But wait! Instead of computers, let’s use lots of smartphones!

Unluckily, security company Lookout says that the math on mobile mining just doesn’t add up.

Mobile Mining Number Crunch

The numbers say it all. Lookout’s researchers calculated that if you’re mining for twenty four solid hours on a Samsung Galaxy SIII, you’d only earn .00000007 Bitcoin or $0.00004473. In order to make just one Bitcoin in a day, Lookout says you’d need 14,285,714 phones working full-tilt at the same time.

Bitcoins are hugely valuable (over $600USD per Bitcoin), and therefore require meaty resources to mine. But even less valuable cryptocurrency, like Litecoin, are beyond the reach of mobile miners. If you took Three,752 SIII phones and let them work for twenty four hours, you’d end up with a single Litecoin which is worth a paltry $8 USD.

Despite the breathtaking odds, Lookout’s principal security researcher Marc Rogers told Security Observe he has seen numerous malicious Bitcoin miners targeting mobile devices. He estimated there was a fresh mining variant detected every month. “The kind of folks who are making mobile malware are very, very inventive,” he said. “Every fresh mining system has a fresh feature. They’re attempting every direction they can to make it profitable, and that’s fairly fascinating.”

Why then do malicious mobile miners persist? Rogers believes that the benefits of the cryptocurrency (it’s free, untraceable, and so on) are simply too tempting for malware creators. There’s also a “cool factor” in attempting to exploit this fresh technology. “Early iterations of mining malware did not seem like serious attempts to be profitable, just playing with the technology and watching what they could do with it,” said Rogers. “But it’s pretty clear that the later versions are deliberate attempts to be profitable.”

Presently, Rogers says that Lookout is witnessing mobile miners attempting to be more discreet in order to distribute their malware to more victims and keep infected phones mining longer. According to Lookout, instead of working your phone until smoke pours out, sophisticated malicious miners only run when connected to chargers, or when the screen is off. Of course, these kinder, gentler malicious miners can’t mine almost as much per day as more aggressive apps.

Of course, there are legitimate Bitcoin mining apps out there, and some developers may be tempted to include mining code in their own applications in the hope of making a little money. However, Rogers says that there is a much simpler way to turn a legitimate profit with mobile apps. It’s called advertising.

Before you crank out, reminisce that Lookout is no friend to malicious or abusive advertising. “Advertising gets a bad rap because we see ad networks that spoil your gameplay or your user practice, but there are good advertising networks out there that are responsible and careful,” said Rogers. “Advertising would be thousands of times more profitable for a developer than mining. There’s a reason ads have powered the mobile ecosystem.”

Case in point, the surprise mega-hit Flappy Bird reportedly earned its creator $50,000 a day in ad revenue.

Mobile Mining Here to Stay

Tho’ Lookout’s numbers paint a bleak picture, Rogers that we’ll see more mobile mining as phones become more sophisticated. “Maybe a fresh phone will come out with a GPU accelerator, so they’ll attempt to use that for mining,” he said. “Every time there’s a fresh option, we’ll see people attempt to leverage it.”

But until you can fit a high-powered computer in your pocket (or a Dogecoin mining NAS), mobile mining will be remain academically interesting but financially plane.
