=====================================
Bitcoin Block Halving prediction
=====================================
bc=944596
gbt=1231006505
bbt=1775914782
This is average time to mine a block
(1775914782-1231006505)/944596
bts=576.8685238255044214622743
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 07:43:51 UTC 2028
-------------------------------------
Next palindrome will be 945549
predicted to happen at this time:
Fri Apr 17 22:22:17 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 15:09:38 UTC 2026
