I don't see any plan, but will you say the same thing when the s= ubsidy

Yes, I forgot the link:


=C2=A0
dwindles, and mining income seems to become uncertain? It will equally
be an economic change, which equally well will have been predictable,
and it will equally well be treatable with a hardfork to increase the
subsidy.

That is a red herring.=C2=A0 N= obody I know has proposed this, and I am opposed to changing that fundament= al.

It is well known that the 1M limit was never i= ntended to stay, unlike 21M coin limit etc.

1M was= set high in the beginning because it is a DoS engineering limit, not an [a= ccidental] economic policy tool.

But I am not against a block size increase har= d fork. My talk on
segregated witness even included proposed pursuing a hard fork at a
slightly later stage.

Great!

But what you're arguing for= is that - despite being completely
expected - blocks grew fuller, and people didn't adapt to block size pressure and a fee market, so the Core committee now needs to kick the
can down the road, because we can't accept the risk of economic
change. That sounds very much like a bailout to me.
