=====================================
Bitcoin Block Halving prediction
=====================================
bc=924608
gbt=1231006505
bbt=1763755893
This is average time to mine a block
(1763755893-1231006505)/924608
bts=576.1888409046418540161300
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 7 01:29:24 UTC 2028
-------------------------------------
Next palindrome will be 925529
predicted to happen at this time:
Thu Nov 27 23:36:02 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Wed Nov 26 17:59:27 UTC 2025
