  When it comes to digital currencies, the choice between using the 'public' or 'external' visibility modifier in Solidity depends on the specific requirements of your contract. The 'public' modifier allows the function or variable to be accessed both internally and externally, making it suitable for cases where you need the function to be accessible by other contracts as well as external entities. On the other hand, the 'external' modifier restricts the access to only external accounts or contracts, which can be useful when you want to limit the access to certain functions or variables. For example, if you have a function that should only be called by external parties, you can use the 'external' modifier to ensure that it cannot be accessed internally. Ultimately, the choice between 'public' and 'external' depends on the specific use case and security requirements of your contract.
