=====================================
Bitcoin Block Halving prediction
=====================================
bc=963334
gbt=1231006505
bbt=1787247796
This is average time to mine a block
(1787247796-1231006505)/963334
bts=577.4121058614085442758749
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 22:16:33 UTC 2028
-------------------------------------
Next palindrome will be 963369
predicted to happen at this time:
Thu Aug 20 23:20:05 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 20:05:03 UTC 2026
