Schroedingers ball
There may be a ball inside the cup, but the quantum superposition of it's existence is only broken down when you place your bet. Does the ball exist or not, it's up to you to implement it's fate.
Predict the future correctly and win.
Even if you don't win, you'll get 500 CUPZ Tokens per STEEM wagered anyway.
Each CUPZ Token you hold gives you a share of all profits made by the app.
