=====================================
Bitcoin Block Halving prediction
=====================================
bc=945224
gbt=1231006505
bbt=1776283009
This is average time to mine a block
(1776283009-1231006505)/945224
bts=576.8748223967838345367505
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 09:34:05 UTC 2028
-------------------------------------
Next palindrome will be 945549
predicted to happen at this time:
Sat Apr 18 00:01:33 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 16:48:53 UTC 2026
