=====================================
Bitcoin Block Halving prediction
=====================================
bc=975671
gbt=1231006505
bbt=1794572939
This is average time to mine a block
(1794572939-1231006505)/975671
bts=577.6187427742110053378594
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 24 10:32:42 UTC 2028
-------------------------------------
Next palindrome will be 976679
predicted to happen at this time:
Fri Nov 20 06:12:58 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Sat Nov 14 00:11:45 UTC 2026
