=====================================
Bitcoin Block Halving prediction
=====================================
bc=934145
gbt=1231006505
bbt=1769644988
This is average time to mine a block
(1769644988-1231006505)/934145
bts=576.6105972728031806591260
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 04:30:08 UTC 2028
-------------------------------------
Next palindrome will be 934439
predicted to happen at this time:
Fri Jan 30 23:08:31 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Fri Feb 6 12:54:32 UTC 2026
