=====================================
Bitcoin Block Halving prediction
=====================================
bc=969571
gbt=1231006505
bbt=1790935314
This is average time to mine a block
(1790935314-1231006505)/969571
bts=577.5010097238781647984884
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 00:12:22 UTC 2028
-------------------------------------
Next palindrome will be 969969
predicted to happen at this time:
Mon Oct 5 01:52:39 UTC 2026
-------------------------------------
Current mining epoch number is 480.
The next fortnight happens in block
969696 and probably around this time:
Sat Oct 3 06:05:01 UTC 2026
