Been in bitcoin since early 2013. Set up a hardware wallet about a year ago and almost didn’t write down my password/pin because it was such a personal number to me I would always remember it. Guess what? I have no clue what it is a year later and just wiped my hardware wallet after too many incorrect guesses. Which was only like five attempts. Never had anything like this happen before in all my bitcoin experience. So.... a warning to everyone that no matter how new or experienced you are, your memory is NOT good enough to store your private key.
