Perhaps there might be some cartell between the big miners and mining hardware companies.
This is the biggest downfall of the blockchain.What if mining becomes so centralized,than only one big mining company remains and controls all the transactions?They can say "Pay 25% fees ,or we will stop mining and confirming transactions."What happens with bitcoin,if there are no transactions?
This is the point guys, we always talk that bitcoin is decentralized but how? There are still cartels controlling mining activities and hardware companies. They're controlling people at the same time. Mining and storage should be free. Fee or other things are belonging to a centralized mechanism.
