=====================================
Bitcoin Block Halving prediction
=====================================
bc=927279
gbt=1231006505
bbt=1765375359
This is average time to mine a block
(1765375359-1231006505)/927279
bts=576.2756168579069968078681
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 8 02:47:58 UTC 2028
-------------------------------------
Next palindrome will be 927729
predicted to happen at this time:
Sat Dec 13 14:04:43 UTC 2025
-------------------------------------
Current mining epoch number is 459.
The next fortnight happens in block
927360 and probably around this time:
Thu Dec 11 03:00:37 UTC 2025
