=====================================
Bitcoin Block Halving prediction
=====================================
bc=934425
gbt=1231006505
bbt=1769832803
This is average time to mine a block
(1769832803-1231006505)/934425
bts=576.6388114200589452776356
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 12:43:53 UTC 2028
-------------------------------------
Next palindrome will be 934439
predicted to happen at this time:
Sat Jan 31 06:27:55 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Fri Feb 6 20:14:25 UTC 2026
