=====================================
Bitcoin Block Halving prediction
=====================================
bc=943959
gbt=1231006505
bbt=1775508956
This is average time to mine a block
(1775508956-1231006505)/943959
bts=576.8278857154964193398025
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 19:52:41 UTC 2028
-------------------------------------
Next palindrome will be 944449
predicted to happen at this time:
Fri Apr 10 03:26:41 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 04:29:15 UTC 2026
