How you want build a masternode network with this colateral input level of 500k MUE ? If MUE cost 2$ masternode cost 1 mil. $  That is more as DASH masternode now.
Why not 10k or 50k. Network need more masternodes then 142 (But now is only ONE masternode online and 45% profit from all blocks go in one hand)
Looks like you want only small amount of masternodes for early adopter or insider. This is against decentralisation concept.
Why? Explain pls.
