=====================================
Bitcoin Block Halving prediction
=====================================
bc=952542
gbt=1231006505
bbt=1780700742
This is average time to mine a block
(1780700742-1231006505)/952542
bts=577.0807585589311978566846
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 17 21:37:58 UTC 2028
-------------------------------------
Next palindrome will be 953359
predicted to happen at this time:
Thu Jun 11 10:03:36 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Fri Jun 12 19:33:46 UTC 2026
