=====================================
Bitcoin Block Halving prediction
=====================================
bc=969648
gbt=1231006505
bbt=1790985791
This is average time to mine a block
(1790985791-1231006505)/969648
bts=577.5072072471585078724363
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 02:00:50 UTC 2028
-------------------------------------
Next palindrome will be 969969
predicted to happen at this time:
Mon Oct 5 03:32:50 UTC 2026
-------------------------------------
Current mining epoch number is 480.
The next fortnight happens in block
969696 and probably around this time:
Sat Oct 3 07:45:11 UTC 2026
