=====================================
Bitcoin Block Halving prediction
=====================================
bc=945978
gbt=1231006505
bbt=1776728776
This is average time to mine a block
(1776728776-1231006505)/945978
bts=576.8862427178616015788934
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 12:53:56 UTC 2028
-------------------------------------
Next palindrome will be 946649
predicted to happen at this time:
Sat Apr 25 11:17:46 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 06:52:14 UTC 2026
