=====================================
Bitcoin Block Halving prediction
=====================================
bc=956018
gbt=1231006505
bbt=1782791380
This is average time to mine a block
(1782791380-1231006505)/956018
bts=577.1693606507820451267181
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 18 23:28:30 UTC 2028
-------------------------------------
Next palindrome will be 956659
predicted to happen at this time:
Sat Jul 4 10:35:45 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Fri Jul 10 17:27:41 UTC 2026
