=====================================
Bitcoin Block Halving prediction
=====================================
bc=935086
gbt=1231006505
bbt=1770275091
This is average time to mine a block
(1770275091-1231006505)/935086
bts=576.7041847443072141950428
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 07:47:55 UTC 2028
-------------------------------------
Next palindrome will be 935539
predicted to happen at this time:
Sun Feb 8 07:38:57 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Sat Feb 7 13:13:37 UTC 2026
