So this is the reason why. I've been searching for the reason. This is why BTC is centralized now because of these mining cartels. They have some power that is well driven by their own will. Decentralization really?
I was disappointed with this incident, too many were victims. especially traders and people who hold altcoins. Decentralized trust in bitcoin has declined. I'm not sure the next year there will be a good development.
I hope there is new hope, in the new year.
