=====================================
Bitcoin Block Halving prediction
=====================================
bc=926745
gbt=1231006505
bbt=1765063786
This is average time to mine a block
(1765063786-1231006505)/926745
bts=576.2714713632430029371586
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 8 01:35:26 UTC 2028
-------------------------------------
Next palindrome will be 927729
predicted to happen at this time:
Sat Dec 13 13:00:37 UTC 2025
-------------------------------------
Current mining epoch number is 459.
The next fortnight happens in block
927360 and probably around this time:
Thu Dec 11 01:56:32 UTC 2025
