=====================================
Bitcoin Block Halving prediction
=====================================
bc=934782
gbt=1231006505
bbt=1770081755
This is average time to mine a block
(1770081755-1231006505)/934782
bts=576.6849097598052168257231
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 02:10:36 UTC 2028
-------------------------------------
Next palindrome will be 935539
predicted to happen at this time:
Sun Feb 8 02:38:25 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Sat Feb 7 08:13:06 UTC 2026
