Is this a joke? Half of your answers are scams and the other half are risky and not a way you would earn money. Seriously, if someone said 'my job is... A slot jockey!' In real life what would you think? That they're a bum! Same thing here. All of those answers are for people that don't understand the value of money (no matter what currency it is). Offer something that's worth people paying you for. Write articles, design something, sell a watch. All of these are legitimate ways to earn bitcoins. Trading is the only legitimate way to earn bitcoins that you have listed and it's so risky for most people because it's just guesses!
Yes the list have a lot of scam(or lose) options but none have votes, trading isn't lucky, that requires knowledge but I doubt that everyone that voted in trading are trading, it's a hard work, I think neither than 1% that people who voted on trading are making some money with it.
Bitcoin attract people who want easy money
Well, at least we can see some votes to "other options", hope it's a normal job.
