=====================================
Bitcoin Block Halving prediction
=====================================
bc=954373
gbt=1231006505
bbt=1781856168
This is average time to mine a block
(1781856168-1231006505)/954373
bts=577.1842726226825123064961
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 03:49:28 UTC 2028
-------------------------------------
Next palindrome will be 954459
predicted to happen at this time:
Fri Jun 19 21:50:05 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 10:12:18 UTC 2026
