=====================================
Bitcoin Block Halving prediction
=====================================
bc=935062
gbt=1231006505
bbt=1770258226
This is average time to mine a block
(1770258226-1231006505)/935062
bts=576.7009506311339449855250
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 06:51:19 UTC 2028
-------------------------------------
Next palindrome will be 935539
predicted to happen at this time:
Sun Feb 8 06:48:32 UTC 2026
-------------------------------------
Current mining epoch number is 463.
The next fortnight happens in block
935424 and probably around this time:
Sat Feb 7 12:23:11 UTC 2026
