=====================================
Bitcoin Block Halving prediction
=====================================
bc=961514
gbt=1231006505
bbt=1786150939
This is average time to mine a block
(1786150939-1231006505)/961514
bts=577.3642990488967930817511
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 08:19:56 UTC 2028
-------------------------------------
Next palindrome will be 962269
predicted to happen at this time:
Thu Aug 13 02:07:29 UTC 2026
-------------------------------------
Current mining epoch number is 476.
The next fortnight happens in block
961632 and probably around this time:
Sat Aug 8 19:57:47 UTC 2026
