This is just like the same as download offers from your site and we earn points that can exchange into bitcoins..
I think this is affiliate from affiliate marketing .. well let me try it in mobile if there is available offer in my country.. and if i have extra data.. i hope there is no need to download something because my internet is data cap..

Update: i dont get any download offers but i redirect from this video..
