A VPN helps protect your Bitcoin transactions from hackers by encrypting your internet connection. When you connect to a VPN, your data is encrypted and routed through a secure tunnel, making it difficult for hackers to intercept or tamper with your information. Additionally, by masking your IP address, a VPN adds an extra layer of anonymity, making it harder for hackers to identify and target your device. Furthermore, using a VPN allows you to connect to servers in different locations, which can help protect against region-specific attacks or restrictions. However, it's important to note that while a VPN enhances your security, it doesn't guarantee complete protection. It's still essential to follow best practices for securing your Bitcoin wallet and use reputable exchanges.
