[bitcoin-dev] New difficulty algorithm part 2

Yes, the current price ratio indicates there is no need for a new
difficulty algorithm. I do not desire to fork before a disaster, or to
otherwise employ a new difficulty before a fork is otherwise needed.

A 2-week delay in difficulty response is a 2 week error in
measurement. Slow response generally means less intelligence.

My goal is not to have a bunch of BTC clones that merchants and buyers
use equally, but to have a  better difficulty algorithm in place to be
used in the next BTC "Core" fork. If not for the current situation,
then for future security.

You mean multiple forks is inflationary. The current limit in quantity
is deflationary because the use of the coin is rising faster than its
mining is producing (see velocity of money). Constant value is defined
as being neither. Bitcoin's deflationary quality created a massive
marketing advantage as well as paid the creator about million dollars
an hour. If it suddenly were able to be a constant value coin, its use
in the marketplace and as a real store of value would skyrocket and
the cries of "Ponzi scheme" would stop. The trick is in determining
constant value without a 3rd party such as an index of a basket of
commodities (which both Keynes and von Mises wanted, but was scuttled
by the U.S. at Bretton Woods).
