=====================================
Bitcoin Block Halving prediction
=====================================
bc=961599
gbt=1231006505
bbt=1786202874
This is average time to mine a block
(1786202874-1231006505)/961599
bts=577.3672722545757071547420
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 09:11:58 UTC 2028
-------------------------------------
Next palindrome will be 962269
predicted to happen at this time:
Thu Aug 13 02:55:10 UTC 2026
-------------------------------------
Current mining epoch number is 476.
The next fortnight happens in block
961632 and probably around this time:
Sat Aug 8 20:45:27 UTC 2026
