=====================================
Bitcoin Block Halving prediction
=====================================
bc=972331
gbt=1231006505
bbt=1792501689
This is average time to mine a block
(1792501689-1231006505)/972331
bts=577.4726986255723353751599
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 15:56:56 UTC 2028
-------------------------------------
Next palindrome will be 973379
predicted to happen at this time:
Tue Oct 27 13:14:40 UTC 2026
-------------------------------------
Current mining epoch number is 482.
The next fortnight happens in block
973728 and probably around this time:
Thu Oct 29 21:13:38 UTC 2026
