=====================================
Bitcoin Block Halving prediction
=====================================
bc=940929
gbt=1231006505
bbt=1773686349
This is average time to mine a block
(1773686349-1231006505)/940929
bts=576.7483702294538382238848
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 20:41:10 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Wed Mar 18 05:53:53 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 09:38:43 UTC 2026
