=====================================
Bitcoin Block Halving prediction
=====================================
bc=940814
gbt=1231006505
bbt=1773611668
This is average time to mine a block
(1773611668-1231006505)/940814
bts=576.7394896977620467360745
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 18:05:45 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Wed Mar 18 03:34:35 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 07:19:22 UTC 2026
