=====================================
Bitcoin Block Halving prediction
=====================================
bc=933266
gbt=1231006505
bbt=1769032445
This is average time to mine a block
(1769032445-1231006505)/933266
bts=576.4973367750065093912031
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 19:28:05 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Thu Jan 22 09:35:29 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 20:38:27 UTC 2026
