After looking intensively on the internet I found this website which is one of the only few ones that pays money to work on it, the concept of it is simple, we have to solve captcha of all kinds and in turn it will pay us through paypal. But the reality hit me once I started using it fully, this site does pay but not as much as its supposed to.
Content wise its a combination of lot of things. There are many kinds of captchas on it, from alphabetic to double lined and also picture based as well, the work is time bound, like with in a limited period of time we have to solve the captcha that appears on the screen. Some times it is really hard to figure out what captcha is on the screen so that makes it hard to work on this.
The sites user interface is very nice, a lot of combination of options are available, like for instance there is a mike notifier option, which notifies the user with a beep sound when a new captcha appears on the screen, so if the user is away from keyboard he will know that its time to work.
Now for the real thing, the usability of this website. The main goal is to earn money but this site provides a very slim ratio of it, which is very unfortunate and disappointing. First of all it gives about 00.0010 - 00.0017 USD per capthca which is very low, and in this rate it would take about two months to just get to 1 dollar. Also the captchas take time to load in two minutes just one number of captcha comes on the screen which is really annoying.
The time it consumes compared to the amount it pays is too much, the payment is too low. There is no point to use this website. I am attaching an image of my earnings, the amount which I have gathered took me two weeks, now imagine how much it would take to gather 1 dollar.
