=====================================
Bitcoin Block Halving prediction
=====================================
bc=943789
gbt=1231006505
bbt=1775406891
This is average time to mine a block
(1775406891-1231006505)/943789
bts=576.8236429714237277360429
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 18:38:26 UTC 2028
-------------------------------------
Next palindrome will be 944449
predicted to happen at this time:
Fri Apr 10 02:19:54 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 03:22:23 UTC 2026
