+1. Also, if you generate a wallet on your computer, NEVER save your private key on your computer or in your password manager. Even in Dropbox. ALWAYS write down your private key on a piece of paper and store it in a safe place.
You're going to write down every private key for every adress you use? Didn't think so.
This isn't practical at all when you're frequently transacting with bitcoin. (As i suspect many here are.) It's an unnecessary hassle ontop of that as well.
Also, what about handwriting/spelling mistakes? A private key is 50+ characters. Misspelling a 5 for an S is easily done..
Absolutely right. My suggest is to use hardware wallet or offline wallet for safety.
