interesting.
Because there it's not said you will be able to sell it. If it is, tell me where or quote it.
It's not said that the coin will be able to be traded. If the coin is attached to the chain, How the hell are you going to trade it??=
It's not said how you can buy a part of the chain (except through a smart contract).
Moreover, it's not said who will be able to enter, and the amount of coins necessary to enter . It's not said the total amount of ETH business in Smart contracts, and who and how owners will be paid for the coins on the chain. It's not said either which % of the income will go to ETH owners or developers.
Also, it's not said which will be the relation between the price in trading market and the price once PoS applied.
Also there it says PoS means decentralization or reduced risk of centralization. but in fact it is centralization, because the chain will be owned by ETH owners, and noone with no coins will be able to enter. Now it's decentralized. With PoS, all will be centralized. The more coins you have, the more centralized on you will be chain.
I can continue crashing your shitty post till the end of heaven, but i think you've had enough for today. Stupid people normally use their brain to not pee in the streets.
