masternodes = 10000 DMD
but, there will also be a POS, which is now 25% per annum, but after launching DMD v3 will become even more.
So, run this past me again
10,000 DMD for a masternode, right? Current supply is 2,172,834 DMD (https://chainz.cryptoid.info/dmd/) = maximum of 217 masternodes if the total supply is used or a maximum of 438 masternodes when DMD reaches 4,380,000 DMD. That just doesn't make any sense. So, you are aiming for maybe 50-60 masternodes running as opposed to around 4000 MNs running for DASH and around 2000 MNs running for PIVX. You should set the collateral much lower. It just doesn't make any sense unless it's just an attempt to push the price up.
I am having the same conundrum with one of my projects. But I think DMD is a holding coin of value. If too much is tied up in Masternodes that is not healthy for the 'liquidity' of the coin. DMD only needs enough Masternodes to secure the network, so yes 50 reliable masternodes may be enough. DMD is not a DASH or PIVX type of coin with high volume darknet trading. DMD is quite different from them.
