Is Leadprizes.com a legit site?

Tweet

I have joined this GPT site called leadprizes.com, and I do its PTC or daily clicks everyday ever since I joined. You know what, no matter how many clicks I done for them on a daily basis, my account balance remain the same, and it never been updated. I just wonder whether I wasted my time in leasprizes, or anyone has any experience with website, is it a scam?
