=====================================
Bitcoin Block Halving prediction
=====================================
bc=975299
gbt=1231006505
bbt=1794311670
This is average time to mine a block
(1794311670-1231006505)/975299
bts=577.5711729724187429508869
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 20:40:14 UTC 2028
-------------------------------------
Next palindrome will be 975579
predicted to happen at this time:
Thu Nov 12 08:49:49 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Fri Nov 13 11:18:09 UTC 2026
