I wish I had know all this information sooner but especially about how to detect a fake email along with the importance of confirming the information all the way.
I was scammed out of $400 because the email was literally one letter off of an email of a person I knew and I fell for it. Granted I was younger then but I felt so stupid. These little details would have been good to know sooner in life.
I also wished I knew all the different ways you can be hacked. I was hacked and blocked out of my instagram account for a couple months because I accidentally clicked on a link I thought was sent by a friend. It is scary how close these scammers get to seem so authentic when they send things.
