=====================================
Bitcoin Block Halving prediction
=====================================
bc=956354
gbt=1231006505
bbt=1782993157
This is average time to mine a block
(1782993157-1231006505)/956354
bts=577.1775669076859534377924
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 01:52:07 UTC 2028
-------------------------------------
Next palindrome will be 956659
predicted to happen at this time:
Sat Jul 4 12:46:36 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Fri Jul 10 19:38:40 UTC 2026
