Recently these kinds of things don't seem legit seeing as bitcoin value just shot up in the last little while. But yeah I was wondering too, for valid sites how much can someone expect to make?
I actually really don't care what is legit or not. Btc has given me an opportunity to do something on the web that i could otherwise not have done. I have bought something with it and its turning into more. as long as I can use it I do not care what it is worth.
The first 2 weeks I got 0.002btc out of the clicking around. I just started advertising and some people signed up. Thats where I am right now.
