=====================================
Bitcoin Block Halving prediction
=====================================
bc=944151
gbt=1231006505
bbt=1775635040
This is average time to mine a block
(1775635040-1231006505)/944151
bts=576.8441257339919843415043
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 00:36:53 UTC 2028
-------------------------------------
Next palindrome will be 944449
predicted to happen at this time:
Fri Apr 10 07:42:19 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 08:45:10 UTC 2026
