=====================================
Bitcoin Block Halving prediction
=====================================
bc=946369
gbt=1231006505
bbt=1776989871
This is average time to mine a block
(1776989871-1231006505)/946369
bts=576.9237887929668100214503
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 23:51:00 UTC 2028
-------------------------------------
Next palindrome will be 946649
predicted to happen at this time:
Sat Apr 25 21:10:09 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 16:45:10 UTC 2026
