How to protect Bitcoin wallets and transaction records?

     Bitcoin is the most vulnerable virtual currency to hackers today , but strict security measures can resist most attacks. So, how to protect Bitcoin wallets and transaction records?

1. Operating system and vulnerability fixes

     The first step to protect your Bitcoin wallet is to use a genuine operating system that is frequently updated with security features and bug fixes. I do not recommend using an Android device to log in to your Bitcoin wallet, because, in my opinion, the Android operating system has many security risks and is easily attractive to hackers.

2. Bitcoin Wallet Client Vs Online Wallet

     The security of most online Bitcoin wallets is questionable. A large number of Bitcoin wallet providers and Bitcoin exchanges have suffered widespread security attacks, and such services are still unable to provide adequate security and insurance for their users. If you must use an online Bitcoin wallet service, use "two-factor authentication" to ensure security.

     Bitcoin wallet clients are the most effective way to ensure the security of your Bitcoins, because only you have the secret key. Don't put all your eggs in one basket, for example, keep a small amount of money on a computer, server or smartphone for daily expenses, and then use "cold storage" to store the rest of the Bitcoins. Both methods must have strong passwords. Multi-signature is another way to increase security.

3. Use a proxy server and VPN

     Proxy servers and VPNs can enhance the security of your Bitcoin wallet. Although most people mistakenly believe that VPNs allow them to surf the Internet anonymously, this is not the case and does not protect privacy. Think of VPNs as "curtains" that only cover the privacy of your house, but your house address will still be exposed.

     A VPN reduces the chances of a hacker gaining access to your router, thus reducing the likelihood of a hacker attack.

4. Anti-phishing browsing behavior

     Always be careful before clicking on any link. As mentioned before, the second time you click on a malicious link your IP address will be logged. Whenever you are suspicious of a link, use the "Phishing Site" service before clicking on it.

5. Encrypt and backup your wallet

     Wallet backups are essential to protect against computer crashes or human error. Encrypted backups can help you protect your Bitcoins in the event that your computer or phone is stolen. You should always encrypt online backups, as even an Internet-connected computer is vulnerable to malicious attacks. Therefore, any backups that can access the Internet should be encrypted.

6. Refrigeration

Offline wallets are sometimes referred to as "cold storage" for Bitcoin. Cold storage is the best way to store Bitcoin that is not connected to the Internet. Cold storage should be used for Bitcoin storage.
