Here are the points :-
- Don't be so casual about your master password, keep it in a safe place, it is highly essential other wise it may land you in a very inconvenient position. Try to write it down in your personal diary offline apart from keeping it safe online.
- Try to use "posting keys" while using steemit, use "master key" only when you want to access your wallet. Why i am saying this, very often by mistake we used to past it in promotion, that may lead to compromising with your stem account.
- Try to keep your earning in saving account, because if your account gets compromised you will get at least three days to find a way out.
- Don't just go for posting only, try to socialize yourself by participating in other posts as well and always give relevant comment/reply, don't try to flood the comment section of other with "ready made comments", else you will be considered as a spammer in Steemit.
