=====================================
Bitcoin Block Halving prediction
=====================================
bc=943337
gbt=1231006505
bbt=1775119905
This is average time to mine a block
(1775119905-1231006505)/943337
bts=576.7958038370128204312770
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 10:31:15 UTC 2028
-------------------------------------
Next palindrome will be 943349
predicted to happen at this time:
Thu Apr 2 10:47:06 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 09:03:21 UTC 2026
