=====================================
Bitcoin Block Halving prediction
=====================================
bc=958926
gbt=1231006505
bbt=1784576004
This is average time to mine a block
(1784576004-1231006505)/958926
bts=577.2801255987160649350784
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 07:46:54 UTC 2028
-------------------------------------
Next palindrome will be 959959
predicted to happen at this time:
Mon Jul 27 17:12:14 UTC 2026
-------------------------------------
Current mining epoch number is 475.
The next fortnight happens in block
959616 and probably around this time:
Sat Jul 25 10:12:07 UTC 2026
