Geez, some people have hobbies, you know. And a couple of lucky few gamers even make more a lot more money gaming than you could with mining.
That's like saying: a couple of lucky few tennis players even make more than you could with mining.
Nice comparison. It's most likely an addiction, not a hobby.
You might as well say mining is an addition then as well. At the prices some of the devices are going (USB block eruptors anyone?) a lot of people are likely wasting money instead of making it.
