=====================================
Bitcoin Block Halving prediction
=====================================
bc=945387
gbt=1231006505
bbt=1776377580
This is average time to mine a block
(1776377580-1231006505)/945387
bts=576.8753940181174290344281
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 09:44:05 UTC 2028
-------------------------------------
Next palindrome will be 945549
predicted to happen at this time:
Sat Apr 18 00:10:33 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 16:57:54 UTC 2026
