You are a liar. P-o-W is open to the public, people can choose to pull hashing power reducing the Transaction process to zero sum. As for Bitmain controlling 30% of the hashing power on SHA-256, that is just a symptom of corporate effort to validate transactions for the long term. There are people all around the world running nodes, these (lightning) nodes guarantee BTC's Decentralization of P-o-W. Please read up on the Difficulty Factor in which the Article neglects to acknowledge being the reason for intensifying hashing power rates of Blockchain Corporations. Nonetheless, miners or master node users make the choice to dedicate power.. no-one tells them to dedicate power to the chain they all choose to. This is how BTC is community driven, and Decentralized...
