I remember a time when earning tank coins actually worked. I mean, a virus or two but at least you still got your tank coins in the end. But now, can't ever find a single working one, and you still get a few viruses!
i don't do surveys because i play on facebook but i don't know when but something new was added for earn if you invite a person you get 3 tank coins lol i got 42 coins just like that
I wouldn't know cause I don't use Facebook. Sorry If you wanted to really do 25 alts on an alt... LOL. Long process for 3 coins per friend.
