=====================================
Bitcoin Block Halving prediction
=====================================
bc=943204
gbt=1231006505
bbt=1775041913
This is average time to mine a block
(1775041913-1231006505)/943204
bts=576.7944487147544807332446
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 10:07:32 UTC 2028
-------------------------------------
Next palindrome will be 943349
predicted to happen at this time:
Thu Apr 2 10:25:48 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 08:42:02 UTC 2026
