=====================================
Bitcoin Block Halving prediction
=====================================
bc=942559
gbt=1231006505
bbt=1774665769
This is average time to mine a block
(1774665769-1231006505)/942559
bts=576.7900865727380750297063
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 08:51:12 UTC 2028
-------------------------------------
Next palindrome will be 943349
predicted to happen at this time:
Thu Apr 2 09:17:13 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 07:33:26 UTC 2026
