=====================================
Bitcoin Block Halving prediction
=====================================
bc=932552
gbt=1231006505
bbt=1768597032
This is average time to mine a block
(1768597032-1231006505)/932552
bts=576.4718219768742366385610
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 12:01:34 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Thu Jan 22 02:58:35 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 14:01:31 UTC 2026
