=====================================
Bitcoin Block Halving prediction
=====================================
bc=934719
gbt=1231006505
bbt=1770036446
This is average time to mine a block
(1770036446-1231006505)/934719
bts=576.6753049041424169804861
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 23:22:31 UTC 2028
-------------------------------------
Next palindrome will be 935539
predicted to happen at this time:
Sun Feb 8 00:08:39 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Sat Feb 7 05:43:22 UTC 2026
