Yes there is an article here somewhere on this blog that proves that writing captcha from a poor country you can actually earn a good income from that, look:

So did anybody learned some security for your bitcoins from my book? Let me hear your feedback guys! 

Don't the free hosts add adverts onto the pages and stuff?

Nah thats just the oldest trick, people know that already, not worth it.

Besides too many people do it already, so the best is just to write captcha!

Hmm this question had been asked in this similar board for countless times now. Might as well check them out before posting another one, but anyway, here are some answers to your question:

Apparently, there are no such things that can be labelled as "easy money" in the current times, be it bitcoin or fiat. If you are one of the guys who knew bitcoin way back 2009 or 2010, you could have make lots of btc by mining and letting your miner hash and give you thousands of btc, or staying here in this forum and participate in giveaways. But that was then, and this is now: in order to gain bitcoins, one must buy it, work for it, or scam for it (though the third isn't acceptable or is recommended). Buying it is the easiest way I can think of if one wants to get involved in bitcoin. Working for it is also similar on having a job, except the fact that you're getting paid in bitcoins or gaining bitcoins in return. This is done by either trading, doing work for others, or by gambling (it still requires work after all.) The yields are good enough if you do not depend your whole life into it. The last one is scamming. How many scam attempts and successful scams have you heard of that happened in bitcoins? I suppose there are numerous, right? Given that bitcoin is pseudo-anonymous and does not require any personal information before anyone can use it, scammers tend to use it as a medium to their scam attempts. If you know how to hide yourself in the internet, know how to code and have a solid plan at your hands, you could easily scam people with their BTC and run away without anyone knowing your identity. Rinse and repeat and voila! You have BTC now!
