There is a key in the config file that identifies the node so you can start it remotely from the cold wallet.

You obviously don't know what a cold wallet is.
A cold wallet is one in which the private keys are NOT stored on a machine with ANY access to or from ANY other machine at all.
So, it is therefore IMPOSSIBLE to "start (a node) remotely from (a) cold wallet."
It is huge failures in basic security concepts that make the D-coin akin to a mirage, and almost like a Trojan Horse, in my opinion.
If you compromize the server running the daemon and get access to the MN private key you still won't be able to touch the 1k deposit.
MN priv keys have nothing to do with addresses private keys.
