=====================================
Bitcoin Block Halving prediction
=====================================
bc=952674
gbt=1231006505
bbt=1780796169
This is average time to mine a block
(1780796169-1231006505)/952674
bts=577.1009672763534258797596
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 18 03:31:37 UTC 2028
-------------------------------------
Next palindrome will be 953359
predicted to happen at this time:
Thu Jun 11 15:24:43 UTC 2026
-------------------------------------
Current mining epoch number is 472.
The next fortnight happens in block
953568 and probably around this time:
Sat Jun 13 00:54:57 UTC 2026
