=====================================
Bitcoin Block Halving prediction
=====================================
bc=942349
gbt=1231006505
bbt=1774548886
This is average time to mine a block
(1774548886-1231006505)/942349
bts=576.7945890592667268000212
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 10:10:00 UTC 2028
-------------------------------------
Next palindrome will be 943349
predicted to happen at this time:
Thu Apr 2 10:28:00 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 08:44:15 UTC 2026
