If you have coins in your wallet, or in a purse, the devil is likely to be significantly more bothersome. That is because coins are often give off certain energies that make them difficult to corrupt. They also make their environment difficult to corrupt.
When you give to the needy, give them coins or give them a gift card that does not need to be activated online, and does not incur monthly charges. They would become much more resistant to demonic activity. The Lord God Almighty hates corruption, wherever it is found.
