=====================================
Bitcoin Block Halving prediction
=====================================
bc=962450
gbt=1231006505
bbt=1786722487
This is average time to mine a block
(1786722487-1231006505)/962450
bts=577.3966487644565801271960
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 17:46:03 UTC 2028
-------------------------------------
Next palindrome will be 963369
predicted to happen at this time:
Thu Aug 20 19:11:54 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 15:56:48 UTC 2026
