=====================================
Bitcoin Block Halving prediction
=====================================
bc=966358
gbt=1231006505
bbt=1789042100
This is average time to mine a block
(1789042100-1231006505)/966358
bts=577.4619939380706342053005
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 12:49:36 UTC 2028
-------------------------------------
Next palindrome will be 966669
predicted to happen at this time:
Sat Sep 12 14:01:30 UTC 2026
-------------------------------------
Current mining epoch number is 479.
The next fortnight happens in block
967680 and probably around this time:
Sat Sep 19 08:11:44 UTC 2026
