=====================================
Bitcoin Block Halving prediction
=====================================
bc=952797
gbt=1231006505
bbt=1780888133
This is average time to mine a block
(1780888133-1231006505)/952797
bts=577.1229872438859023633550
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 18 09:56:58 UTC 2028
-------------------------------------
Next palindrome will be 953359
predicted to happen at this time:
Thu Jun 11 21:14:36 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Sat Jun 13 06:44:54 UTC 2026
