How much money/stake is required to be fully part of the Network and take part in consensus/governance? Should be very affordable for most/all visitors who wish to be fully part of the network. If not,  you can't really call it a truely Decentralized Network. It has to be Decentralized enough to let anyone easily run full node and take part in full network consensus. That's a good Principle (Satoshi's Bitcoin standard) truely Decentralized Cryptocurrencies should be based on.
