So is the argument that the "block reward going to zero means bitcoin's security budget will be insufficient" dead now?
Discussion
Nope. It comes back every bear market. It will die down for a year or two though.
It always was.
Everyone alive now will be dead when block rewards stop, so to that extent it was always a moot point anyways. Just fud spread by greedy people trying to get you to buy their crap coin.
