Another of my stupid questions:
All manuals on masternodes are saying how ports should be closed and how root account should not be used.. Personally I use root login with 15 chars long password and cold wallet set-up and did not bother closing the ports - can ANYTHING really happen to me?
My guess is 99.9% not but still would like to get a second opinion. Everyone is saying how root should not be used but I do not see the danger with the cold wallet & decent pw.
Just out of curiosity, why did you opt to use root? It would have taken maybe 10 seconds to add a new user and give it a password, log out of root, log in to your new non-root user, and install. Also, not sure who you are using for a VPS, but there are iptables that you can literally copy and paste for both AWS and Vultr.
