A good set of tips but you can't confine all the stuff in one place.
We must all continue to question and research, nothing is perfect.
I can add these points:
 
 - Read Forum Rules: This advice will secure your account first and you will be able to learn a lot of things about this forum.
 - Do not randomly click on any link: Many links lead you to scam websites or download viruses to your computer.
 - Do not download any untrustworthy wallets/apps: This includes closed source and the new wallets/apps "Hosting on Github will not change anything."
 - Do not trust anyone: review each piece of information before using it.
