=====================================
Bitcoin Block Halving prediction
=====================================
bc=933290
gbt=1231006505
bbt=1769043375
This is average time to mine a block
(1769043375-1231006505)/933290
bts=576.4942231308348628669943
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 18:33:35 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Thu Jan 22 08:47:03 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 19:50:01 UTC 2026
