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.
That's the dark part of this project as per their latest token economics paper before moving from matic to polygon 80% of tokens are team, founders and network related. They did not update that paper since and there are questions on network sustainability once token supply stops.
