Everyone knows that bitcoin will become just like fiat currency once it all belongs to the government's hands. But that's not going to happen in reality. Whales wouldn't sell their coin to the government even if the price is starting to pump really hard because the government is buying bitcoins. Yes, they have to buy bitcoins since they can't just take it away from us. They don't have any power here and they can't even attack someone since it's decentralized or hack the network.

For me, bitcoin will never be centralized even if the government put some law about the use bitcoins. There would always be people like me that wouldn't sell coins to the government to preserve the decentralization feature of bitcoins.
