Staking/node privacy-secure?

[marimanga]

Currently im staking an "X" coin and its doing pretty good regarding staking.. at this moment devs of X coin released an article on how to setup a node and im stuck because i don't understand some things if you could help me that would be great.

I'm using Linux and before running a node from private computer below are devs statement from article they published and my questions.

Devs statement

1. Do not use your public node to store your "X Coin" or for staking. Stake from a separate computer, if possible.
* What happens if i store X Coin , run a node and staking in same Computer?

2.Your firewall should have a single port (xxxxxx) open to the outside world, and physical access by unauthorized users must be prevented.
* Would it be possible for someone to access my wallet through nodes and spend X Coin?

3. Do nodes cost electricity?

4. If i run a node would it be more profitable than staking?

I'm not interested buying hosted nodes.


Thank you.

Which coin?  X coin doesnt match anything i can find.  Hard to help when its a mystery coin.

1) The reason they recommend not storing your coins on your node is because your node will be exposed to the network.  Safer for your coins to be not on the machine running the node.

2) They are suggesting and its good advise to limit the ports open to the internet through your router/firewall.  All of this it to try to prevent unauthorized access to your machine.

3) Sure all computers running consume power so will the node computer.

4) Cant answer without knowing what coin.

I never recommend buying things you can do yourself.
