=====================================
Bitcoin Block Halving prediction
=====================================
bc=945669
gbt=1231006505
bbt=1776546911
This is average time to mine a block
(1776546911-1231006505)/945669
bts=576.8824283312360548605750
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 11:47:11 UTC 2028
-------------------------------------
Next palindrome will be 946649
predicted to happen at this time:
Sat Apr 25 10:17:35 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 05:52:00 UTC 2026
