What's the advantage of me running a stormnode apart from helping the network? And can you bail and take you 1000 coins if you decide to stop or whatever?
Yes the 1000DSLK are simply locked as collateral to the wallet during the time it is ran as a Stormnode.
You can take your collateral at anytime.
Stormnodes return an ROI of 37.7% which is currently 3x Dash's return on Masternodes.
