=====================================
Bitcoin Block Halving prediction
=====================================
bc=932861
gbt=1231006505
bbt=1768779641
This is average time to mine a block
(1768779641-1231006505)/932861
bts=576.4766235520366356438572
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 13:25:36 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Thu Jan 22 04:13:16 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 15:16:13 UTC 2026
