=====================================
Bitcoin Block Halving prediction
=====================================
bc=949473
gbt=1231006505
bbt=1778823762
This is average time to mine a block
(1778823762-1231006505)/949473
bts=576.9692029481586646922401
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:05:45 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 09:59:59 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:48:31 UTC 2026
