I still feel that confiscating stale addresses is what will be done.
How many 2009 to 2010 blocks have zero withdrawals a lot maybe 10,000 blocks of 50 coins each were never touched.
Put in a 2079 year rule that untouched blocks for 2009 will be slowly emptied starting in year 2089 unless a withdrawal is made from an untouched
block.
Banks already do this.
and goverenments allow it.
It is still the same 21 million coins.
With state after state and countries governments making reserve account I am pretty sure we are going to see a push for this.
I will be long dead in 2079 (age of 122) so I won't live to see it happen or most likley I won't even see serious discussion on this as I will likely be
dead by 2057 (100 years old) rewards would be 0.01220703
