=====================================
Bitcoin Block Halving prediction
=====================================
bc=940873
gbt=1231006505
bbt=1773653493
This is average time to mine a block
(1773653493-1231006505)/940873
bts=576.7477770668548604807870
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 20:30:47 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Wed Mar 18 05:44:35 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 09:29:24 UTC 2026
