And a Masternode is just a wallet with some linked collateral, I regularly use a wallet that happens to also 'be' a Masternode.
Well ofcourse the daemon is just the same for wallet and masternode, but they run in a different mode, right?
But it's not like with darkcoin you had your QT-wallet on your home-pc act like a masternode, right? But maybe SPR will allow for that.
(sorry for the dumb questions, I never ran a masternode, but I plan to, soon, side by side with a SPR node, :-) )
The QT client is just the daemon with some GUI stuff on top, you can run a MN via the QT just fine, but then your CPU/RAM/HD etc. requirements are all double because you need all the extra stuff for the GUI client to work, so you're having to run/rent a beefier server... why bother? It's easier and cheaper to use the CLI daemon.
Nothing stopping you from running a MN at home using the QT client if that's what you want to do though.
