=====================================
Bitcoin Block Halving prediction
=====================================
bc=952399
gbt=1231006505
bbt=1780608752
This is average time to mine a block
(1780608752-1231006505)/952399
bts=577.0708179336413271734565
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 17 18:44:00 UTC 2028
-------------------------------------
Next palindrome will be 953359
predicted to happen at this time:
Thu Jun 11 07:25:39 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Fri Jun 12 16:55:47 UTC 2026
