Masternodes will have the blockchain located in different areas and help to decentralize and protect DNRs ledger. It will also require people to lock up a good number of coins (5k) to run one which can be liquidated at any time. You dont want it too easy and you want long term investors getting these to keep it stable. People who run masternodes will get 33% of the block mined spread out over the MN operators which makes it like another little mining rig of passive income. If enough nodes are there it will greatly enhance the value. Probably at time of MNs price will be 2$ or more and then locking up the currency may boost it to 3-5$ this will be great for value and with the new respect well get more people using and enjoying the instant transaction times and people will use DNR between exchanges etc we could have a 10-20$ coin here in a years time! Im sure I missed some but hope that helps
