=====================================
Bitcoin Block Halving prediction
=====================================
bc=933677
gbt=1231006505
bbt=1769292774
This is average time to mine a block
(1769292774-1231006505)/933677
bts=576.5223867328993507397625
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 11 02:46:27 UTC 2028
-------------------------------------
Next palindrome will be 934439
predicted to happen at this time:
Fri Jan 30 00:14:44 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Thu Feb 5 13:59:18 UTC 2026
