=====================================
Bitcoin Block Halving prediction
=====================================
bc=963692
gbt=1231006505
bbt=1787466598
This is average time to mine a block
(1787466598-1231006505)/963692
bts=577.4246497587924785175361
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 01:56:04 UTC 2028
-------------------------------------
Next palindrome will be 964469
predicted to happen at this time:
Fri Aug 28 11:07:36 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
