It is true, my friend, that common sense is necessary no matter what one does. Not giving out your private key to anyone is one of those things that we can control.
However I must point out that there are things out of our control that can come into play. There are Keyloggers looking to steal ones credentials for log ins, clickjacking, screen scraping, and other devious hacking methods. CryptoDefender helps you protect against all of that. It not only protects your crypto wallets, but also your entire computers and mobile devices. The demo can show you how easy it is for a keylogger to gain access to your wallet, as an example.
