Because as soon as it becomes centralized it'll cease being Bitcoin, won't it? I've always thought BTC is decentralized by its nature and hierarchy. If it is, how can it be centralized, anyway? Is that possible at all?
Don't worry dude, nothing will change the nature of bitcoin, even if it's a government. the government can only provide rules for data verification later,
but they will not be able to force it because of anonymous users, centralization is only present when you join in exchanges under the government
They can. Through mining.
We are waiting when there is a mining giant with the largest hash rate in the network. We begin to regulate crypto currency. We hang tax collections on traders and miners. The main pool with a big percent hash rate offers benefits for mining. You will receive a state-controlled system in which it will be able to block transactions, and monitoring exchanges - attaching data from bank cards to bitcoin wallets.
