=====================================
Bitcoin Block Halving prediction
=====================================
bc=944296
gbt=1231006505
bbt=1775714123
This is average time to mine a block
(1775714123-1231006505)/944296
bts=576.8392973820736484389974
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 23:12:24 UTC 2028
-------------------------------------
Next palindrome will be 944449
predicted to happen at this time:
Fri Apr 10 06:26:19 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 07:29:04 UTC 2026
