Worst App to earn money. Review on GrabPoints

I have downloaded this app and I'm using it since 5 months but still I have earned a very less amount I think this is the worst app I think which gives us offers to earn money. The concept of this app is very bad as it do not gives us rupees or dollars it gives us points on completing offers which can we later convert into rupees. It gives us a very less amount of rupees on completing offers. If we complete small offers then we can only get 10 points which equals to Rs. 0.00001 approx. This app is full of bugs as sometimes it do not gives points on completing offers. We can only waste time here. It asked me to make a video on GrabPoints and upload it to YouTube because it was about to give 500 points if we make a YouTube video on Grabpoints. So I made a video and uploaded it to YouTube but even fter 48 hours I didn't get a single point. So, using this app is a waste of time and this app is of no use. I would not like to recommend it to other peoples.
