=====================================
Bitcoin Block Halving prediction
=====================================
bc=946107
gbt=1231006505
bbt=1776812354
This is average time to mine a block
(1776812354-1231006505)/946107
bts=576.8959241439666507417757
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 15:43:22 UTC 2028
-------------------------------------
Next palindrome will be 946649
predicted to happen at this time:
Sat Apr 25 13:50:31 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
