Yes am also having issues with electricity as well, like today now, they have not given us light since morning and I don't even know when they would bring it. The cost of fuel is not also helping matters. Does in top tier countries, it would be easier for them to make a dollar or more from surveys alone, I can't really say for sure if we here can make a dollar per day but it mostly depends on the amount of task you do per day.
I just clicked on the link and saw that there is indeed a private key puzzle which is most likely going to be difficult to crack but I do not think that the 100 erg would indeed be the reward for it, that's a lot of money.
Well an average American may not be able to survive on $1 because the standard of living there is very high compared to here.. They can really make up to $5 a day from survey but that is still a little amount of money because that won't even cover their transport.
You have a point though but you know the dollar has more value then our currency, there are actually things you can can buy in cents, this gives it more value but here you can't even find anything to buy with 10 naira not to mention 5 naira. Kobo is completely out of the question.
Okay I know this is true but do you really think that they have to depend on that ? because most Americans are not really interested to post on forums like we do, I will believe 1 dollar may be able to buy a chewing gum but over here it can gives you a full breakfast.. This won't be possible over there.
