While considering private key safety many suggestions have already been mentioned in posts, but still private keys are the ultimate source to access crypto electronically, without a private key no one can get access to crypto assets. So keeping them safe and secure is the most important task.

As Gmail, any drive, or any cloud services are third-party completely and completely centralized services that may keep watch on data stored electronically, so never keep any confidential data on electronic platforms. It may bring trouble.

The second important task to keep your wallet safe is never to use your wallet for suspicious sites by allowing to access them.

Many phishing sites have extra scripts embedded within websites that get access to the wallet and may harm your equity.
