The point is, many people that come here doesn't have money to buy BTC. They want a job, a way to earn BTC (money). I think buy bitcoins can be a good way to increase your money on long term, but most people want immediately money without big investiments because they don't have money for it.
Exactly.
Maybe not everyone can afford to buy bitcoins like me, so they will look around for methods to earn bitcoins by themselves without investing any money from their pockets.
And there are a lot of ways one can earn bitcoins, so i don't think if someone has time then he will have to buy bitcoin, unless he is willing to do trading with that bought amount.
