=====================================
Bitcoin Block Halving prediction
=====================================
bc=925052
gbt=1231006505
bbt=1764021937
This is average time to mine a block
(1764021937-1231006505)/925052
bts=576.1998847633595048067516
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 7 04:42:40 UTC 2028
-------------------------------------
Next palindrome will be 925529
predicted to happen at this time:
Fri Nov 28 02:26:24 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Wed Nov 26 20:49:47 UTC 2025
