=====================================
Bitcoin Block Halving prediction
=====================================
bc=975380
gbt=1231006505
bbt=1794366245
This is average time to mine a block
(1794366245-1231006505)/975380
bts=577.5791613738631365589446
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 23:00:02 UTC 2028
-------------------------------------
Next palindrome will be 975579
predicted to happen at this time:
Thu Nov 12 10:59:43 UTC 2026
-------------------------------------
Current mining epoch number is 483.
The next fortnight happens in block
975744 and probably around this time:
Fri Nov 13 13:28:03 UTC 2026
