=====================================
Bitcoin Block Halving prediction
=====================================
bc=963255
gbt=1231006505
bbt=1787199686
This is average time to mine a block
(1787199686-1231006505)/963255
bts=577.4095162656656174474905
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 21:31:14 UTC 2028
-------------------------------------
Next palindrome will be 963369
predicted to happen at this time:
Thu Aug 20 22:38:30 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 19:23:27 UTC 2026
