www.coinworker.com is where I got all my coins from.  I got them all from doing the same task, it is the task I mentioned above, you get 10 points every time you finish it, and they send you coins within 15 minutes after you reach 180 points, which i think is around 0.016 BTC, I have completed that same task over 100 times now, I am 30 points away from my next withdraw.  It is pretty simple the task, you just have to find out companies and there parent companies.  They give you like 120 minutes per task, but it takes me about 2 to 3 min to finish each one.  If you know a bit about businesses it helps, but memory works good to because lots of the companies repeat in the task.  It only takes so long, because you have to click on so many links per question to prove you looked it up.  But it has proven to be the easiest for me, and i get more coins for doing this one task then anything else.  I think there is like 4500 of this task still available, so better get going, i dont know if i will find another easy well paying task like this again.
