Whether people want to admit it or not, this coin is fairly centralized due to the 3 million supernode requirement. It's my one criticism with NEM, just like I criticize Xtrabytes for having all their static nodes tied up in the hand of early investors who got the coin for next to nothing. Of course, if you make the supernode requirement 250K, a lot of early supernode holders might dump a bunch of NEM. If that happens it will be a healthy thing in the long haul.
Have to think 10 steps ahead, not worry about maintaining the status quo and the current market cap.
I do agree starting off as POW attracts the huge 'miner' mostly bitcoin community. These guys have the funds to invest in other coins. Without POW, NEM is often overlooked ... but then again NEM is not targeting the crypto community
Also, what average individual can really 'mine' bitcoin? Which shows it is much more centralized when 1 miner pool/individual can do so much damage with the current bitcoin debate/drama.
With NEM, only 10,000 is enough to harvest and as the network grows and txs increase, each block will hold more and more valuable fees. So 3 million won't be required to harvest and profit, you can even do this with your PC off!
The supernode program wont last indefinitely, it was created to secure the network which it has done successfully, I really dont see them dropping the requirement.
Whales have been buying as the # of supernodes continue to increase, just like this guy:
