POS-coins are more like exclusive circles of traders while pow is open for everybody even later in the game.
How is this even the case? How can you jump in the mining game in bitcoin anymore? it's centralized in china for a long time so im just wondering how it's possible in your mind to get started with mining in 2017, that's ridiculous.
At the end of the day, in both POS and POW, it's the same, you need to invest millions to have a say in the mining game.
