Mining is also supposed to be decentralized and yet, we see people closing down their farms...
Decentralized means it keeps working after someone shuts down their farm.It is not decentralized if all the farms have to follow the same orders coming from a singe centralized authority, which is the gubbermint.
The gubbermint: -Do not mine block #13123313123123, that is a federal order.
The miners: -Sir yes sir!
They only need to order the biggest 3 or 4 pools and there goes your decentralized mining.
