"At 0.0004 bitcoins per video it would take 2500 videos to watch to make one bitcoin."
You seem confused by the divisibility of bitcoin.
His goal is not to make one whole bitcoin, but probably to watch ~100 videos (3-4 hours total?) which is 0.04 bitcoins which is enough to buy a meal (~$5).
Also the article is poorly worded but it sounds like the homeless guy is not taking advantage of the 0.000133 btc per day offer (it says "he can beef up..." but should be "he could beef up...")
I just glanced at the FAQ on the services website, and it sounds like the offers pop up from time to time, so you might not be able to watch one video after the other, you have to wait for them to come in. My guess is that the $0.60 day that they quoted is an average of sorts, with some days a bit higher and some lower. Regardless, that is not a lot of money, could take you two weeks of work to buy one pizza.
