=====================================
Bitcoin Block Halving prediction
=====================================
bc=967731
gbt=1231006505
bbt=1789842486
This is average time to mine a block
(1789842486-1231006505)/967731
bts=577.4697757230307564490995
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 15:05:46 UTC 2028
-------------------------------------
Next palindrome will be 967769
predicted to happen at this time:
Sun Sep 20 00:33:49 UTC 2026
-------------------------------------
Current mining epoch number is 480.
The next fortnight happens in block
969696 and probably around this time:
Fri Oct 2 21:40:14 UTC 2026
