=====================================
Bitcoin Block Halving prediction
=====================================
bc=932490
gbt=1231006505
bbt=1768554039
This is average time to mine a block
(1768554039-1231006505)/932490
bts=576.4640452293909539073299
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 09:45:28 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Thu Jan 22 00:57:36 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 12:00:32 UTC 2026
