I agree with your statement, I always use that Golden rules.
System Protection: Always have an anti virus program on your pc. You are traveling into very infected waters where people are trying to steal your info. Run system scans frequently and try not to type passwords directly into websites. I use a program called Roboform which stores all of my passwords and use a program called KeyScrambler to protect against keyloggers. I use a program called malwarebytes that checks for any suspicious activity on my pc. It is a free program. Also, clear your cookies frequently as well. I use a program called CCleaner and it is free as well. I highly recommend adding all of these programs as a bare minimum
and this one I've known it from you. my account was hacked, And my investment gone.
Ill follow this rules by now.
