=====================================
Bitcoin Block Halving prediction
=====================================
bc=940242
gbt=1231006505
bbt=1773214556
This is average time to mine a block
(1773214556-1231006505)/940242
bts=576.6680007189630765663769
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 21:14:42 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Tue Mar 17 08:53:13 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Thu Mar 19 12:37:37 UTC 2026
