Basically it means that more ETH has been destroyed forever than it has been mined.
I don't think that this is anything exciting, it's just for more of an attention grabbing headline than anything else.
People are quick to jump to conclusions and hype up anything and everything imho. This is certainly a one-off event that is going to not be a very impactful event going into the future i think.
Well, its indeed exciting! Of course there is way too eraly for conclusions, but i hope that
the st*pid miners now see the point of previous forks.
