Can you imagine? You just need to very clearly put the coin in the audience's hand. Let him close his hand, then open. The coin changes color. You don't need to do anything. Then the audience can immediately check. This is C-COIN by Zhao Xinyi.

• Less operations
• Reset immediately
• Multiple routines
