=====================================
Bitcoin Block Halving prediction
=====================================
bc=924628
gbt=1231006505
bbt=1763766843
This is average time to mine a block
(1763766843-1231006505)/924628
bts=576.1882203564889269101445
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 7 01:18:32 UTC 2028
-------------------------------------
Next palindrome will be 925529
predicted to happen at this time:
Thu Nov 27 23:26:28 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Wed Nov 26 17:49:53 UTC 2025
