=====================================
Bitcoin Block Halving prediction
=====================================
bc=952254
gbt=1231006505
bbt=1780519765
This is average time to mine a block
(1780519765-1231006505)/952254
bts=577.0652398779738620432552
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 17 17:06:23 UTC 2028
-------------------------------------
Next palindrome will be 952259
predicted to happen at this time:
Wed Jun 3 21:37:30 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Fri Jun 12 15:27:08 UTC 2026
