i'm sure you would agree that amount of energy required to find signatures at 0 difficulty is negligible
> And every year it gets harder, by design (to control the volume of new btc).
no, it doesn't get harder "by design", it gets harder because bitcoin is an instrument that has created a market where financial security can be purchased in form of energy, so it gets harder because that kind of security has value on the market and users keep purchasing it.
> But of course you know that. I wonder why the trollish comments.
turns out you were wrong in your assumptions, yet you proceeded to call me a troll. how about not doing that in future?
