I just discovered the concept of master nodes and found MonacoCoin to be a nice coin for a master node. Can I quit running a master node whenever I want without loosing Money or am I bound to run it forever if I start one? I would like to test it and to see how it works. I know I must get at least 1000 XMCC and put it in a wallet on a server. I might be able to afford that. Is that all? Or is there some hidden cost other than the cost of the server?
