     #### Which visibility should I use ?
 
     A simple answer to this is , start with giving every variable a `private` visibility then as you move further in contract developement modify variables to `internal` visibility as a next step of modification. Try to use `public` visibility as little as possible in order to be gas efficient and making less vulnerabilities in the smart contract.
