Not only LISK is not democratic.
You can see other crypto based on POS. For example to have a masternode on Dash, you need - 323.000 $, on NEM - 600.000$, on Waves - 4500$, on PIVX 382.000 $ …
But you can mine POS with Peercoin only with 1 PPC.
Viva Peercoin !
But Dash is not PoS. I don’t think masternodes are PoS anyway.
It’s just masternodes, who do masternode things.
