=====================================
Bitcoin Block Halving prediction
=====================================
bc=975725
gbt=1231006505
bbt=1794614176
This is average time to mine a block
(1794614176-1231006505)/975725
bts=577.6290382750895230833246
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 24 13:32:52 UTC 2028
-------------------------------------
Next palindrome will be 976679
predicted to happen at this time:
Fri Nov 20 09:00:34 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Sat Nov 14 02:59:10 UTC 2026
