Poor people are taking advantage of. Very sad, very sad indeed. There are also alot of people in China and other locations in Asia doing similar things. Internet advertisement is indeed fully unreliable. Not only that, this whole thing makes running a Web site more expensive without actually bringing in any income. Only useless traffic.
One might even say that the old Internet as we knew it is long gone.

Homeless, unemployed, and surviving on watching and clicking on advertisemen.
The park offers free wireless access, and with his laptop, Angle watches YouTube videos in exchange for bitcoins, the world's most popular digital currency.
For every video he watches, Angle gets 0.0004 bitcoins, or about 5 cents, thanks to a service, called BitcoinGet, that shamelessly drives artificial traffic to certain online clips. He can watch up to 12 videos a day, which gets him to about 60 cents. And he can beef up this daily take with Bitcoin Tapper, a mobile app that doles out about 0.000133 bitcoins a day - a couple of pennies - if he just taps on a digital icon over and over again. Like the YouTube service, this app isn't exactly the height of internet sophistication - it seeks to capture your attention so it can show you ads - but for Angle, it's a good way to keep himself fed.
