We always often hear a sentence: Don't Trust, Verify. Even the sentence does tend to be bitcoin, but if you study it carefully that sentence is very useful to remind us not to easily believe in something in the world. We are humans who are sometimes careless and forget about something which can make us lose something important. Because of that if I receive something via email, Chat, SMS, or anything on the gadget, I have to check it 1st if that message is safe from viruses, or any kind of malware. I never click on any links from messages even if the links look clean and trust. I will definitely ask and find out the purpose until I'm really sure that link is safe. Sometimes, If the link is useless for me, I never click it even if it's safe.
