If you have enough Arctic Coin for 2 or more goldminenodes, what would be the best way to go about it? 

Running multiples on the same machine 1000 one address, 1000 next address same wallet config with seperate entries for each address/node key etc.

Or 2000 for a single node (and would that offer any advantage) or is that even possible? 

Would the best approach be to run nodes on separate dedicated machines?

Thanks in advance!
