=====================================
Bitcoin Block Halving prediction
=====================================
bc=972783
gbt=1231006505
bbt=1792763616
This is average time to mine a block
(1792763616-1231006505)/972783
bts=577.4736334067994539383871
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 16:13:17 UTC 2028
-------------------------------------
Next palindrome will be 973379
predicted to happen at this time:
Tue Oct 27 13:29:50 UTC 2026
-------------------------------------
Current mining epoch number is 482.
The next fortnight happens in block
973728 and probably around this time:
Thu Oct 29 21:28:48 UTC 2026
