=====================================
Bitcoin Block Halving prediction
=====================================
bc=940598
gbt=1231006505
bbt=1773463440
This is average time to mine a block
(1773463440-1231006505)/940598
bts=576.7143437320260812524784
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 10:45:42 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Tue Mar 17 21:00:09 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 00:44:48 UTC 2026
