I think Masternodes would be awesome for Spreadcoin. How many Spread would you need to run a MN, or is this to early to ask?
yes,masternodes are awesome ,but before that,availabilty and security are the first things to consider.
BTW:Do masternode need any cost
Masternodes will be PROFITABLE to run. My suggestion, if Mr Spread implements them, would be to have them require 1000 SPR in their connected wallet to run (just like DRK). You don't lose that SPR, you can withdraw it anytime, but if you do, the masternode is no longer active.
You need a VPS to run masternodes as well so there is that monthly cost. However, masternodes would get a portion of each block's mined SPR. As such, masternodes should inherently be profitable to run.
They also cause the price of the coin to rise because people buy it to get masternodes and take those coins out of circulation.
