Plarium makes money regardless if no one spends money on game. The people who go on everyday makes a paycheck for Plarium. So this game dont get shutdown due to anyone not spending on it.Jezebel makes a good point. Plarium HAVE to show a profit or the game will be shut down. The coiners are paying $$$'s so the smarter ones of us can play for free. If that gives them top rankings in tournaments, so be it, they pay heavily for that privilege. (Bots in the rankings is a whole different story.) As Jez says, this game is fun to play without coining.
So I say "Go hard coiners. Keep this game free for me for as long as you can."
