Does Airgap Make Bitcoin Hardware Wallets More Secure?

There are several important factors that make a Bitcoin hardware wallet more secure. The first is whether it is air gapped. If it is, it reduces the attack surface by preventing data exchange. If it is not, it can be hacked. Another factor to consider is whether the hardware wallet uses a power bank to display the receive address on its screen.

Unlike software wallets, hardware wallets keep private keys offline. The main advantage of air-gapped wallets is that they are fully isolated from USB, Bluetooth, WiFi, and Cellular connections. As a result, the wallet is not exposed to malware.
