Nano uses dPOS and does not mint any new coins with PoS nor does not charge any tx fees. Instead of "Give the rich more money" it's more like "preserve the value of my money by fulfilling the promise of this coin".
Nano/Raiblocks were created from software, a reproducable distributed database protocol. Except in the case of Nano, the vast majority of the tokens are in control of the owners with a few being given away to the public for clicking captchas.
What evidence is there 90% of Nano distribution isn't owned by a single person?
This is a major aspect of transparency in decenteralized p2p protocols, and the issue with Nano is there's no paper trail or proof that the devs didn't take all the supply.
We do know 13% of all Nano in circulation was stolen in the Bitgrail hack.
