When you're setting up a masternode do you ever import your masternode private key into your vps? Is anything stored on your vps that if someone found it they could steal your coins? Also, if someone was able to see your terminal window when you were setting up a MN would there be anything they could do to steal your coins? I looked at Tao's guide and it doesn't seem like it to me, but I just want to be sure.
If you're using tao's guide you have nothing to worry about on the vps side. Even if someone was able to see your input it doesn't reveal anything that can be used to get at your coins.
