=====================================
Bitcoin Block Halving prediction
=====================================
bc=948569
gbt=1231006505
bbt=1778307570
This is average time to mine a block
(1778307570-1231006505)/948569
bts=576.9748832453060923284523
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 14:45:09 UTC 2028
-------------------------------------
Next palindrome will be 948849
predicted to happen at this time:
Mon May 11 03:12:02 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 17:18:24 UTC 2026
