You get 50%+1 then you can make whatever rules you want....so.....its up to you.
False. Having +1 over 50% does not grant you title like that. This is a common misconception. Rather, the more of the hashing power one controls, the more likely it is that he/she can fork the blockchain and alter things. It's a gradient with a focal point at the 50% mark... but the 50% mark is not a guarantee of takeover.
Thanks for correcting me on that. It was a bad strategy anyway the more I think about it. Better to think the mechanism is to adopt another cryptocurrency or get invloved in world govts. The thing about changing it is we end up with the US dollar in the long run.
