=====================================
Bitcoin Block Halving prediction
=====================================
bc=961951
gbt=1231006505
bbt=1786418732
This is average time to mine a block
(1786418732-1231006505)/961951
bts=577.3803963191510595123249
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 13:01:38 UTC 2028
-------------------------------------
Next palindrome will be 962269
predicted to happen at this time:
Thu Aug 13 06:25:38 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 11:35:46 UTC 2026
