=====================================
Bitcoin Block Halving prediction
=====================================
bc=945827
gbt=1231006505
bbt=1776630788
This is average time to mine a block
(1776630788-1231006505)/945827
bts=576.8747414963397150433271
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 09:32:40 UTC 2028
-------------------------------------
Next palindrome will be 946649
predicted to happen at this time:
Sat Apr 25 08:16:19 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 03:50:36 UTC 2026
