=====================================
Bitcoin Block Halving prediction
=====================================
bc=952634
gbt=1231006505
bbt=1780767055
This is average time to mine a block
(1780767055-1231006505)/952634
bts=577.0946375054454224335658
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 18 01:40:51 UTC 2028
-------------------------------------
Next palindrome will be 953359
predicted to happen at this time:
Thu Jun 11 13:44:08 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Fri Jun 12 23:14:21 UTC 2026
