=====================================
Bitcoin Block Halving prediction
=====================================
bc=934034
gbt=1231006505
bbt=1769557777
This is average time to mine a block
(1769557777-1231006505)/934034
bts=576.5857510692854122168869
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 11 21:15:20 UTC 2028
-------------------------------------
Next palindrome will be 934439
predicted to happen at this time:
Fri Jan 30 16:41:34 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Fri Feb 6 06:27:11 UTC 2026
