I use the mobile app to watch videos every day. Each day the big wheel spins and gives me an award of some amount of coins. I don't have very many of the; only a few more than 159,000. Now if WGT would give these coins some value, say 1 credit for every 100 coins, I could see a reason to accumulate them. But for now, since I don't play on my mobile app where the coins can be wagered, they are useless.
