=====================================
Bitcoin Block Halving prediction
=====================================
bc=945063
gbt=1231006505
bbt=1776186406
This is average time to mine a block
(1776186406-1231006505)/945063
bts=576.8708796441299213598232
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 08:25:05 UTC 2028
-------------------------------------
Next palindrome will be 945549
predicted to happen at this time:
Fri Apr 17 22:59:25 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 15:46:46 UTC 2026
