=====================================
Bitcoin Block Halving prediction
=====================================
bc=940762
gbt=1231006505
bbt=1773568004
This is average time to mine a block
(1773568004-1231006505)/940762
bts=576.7249551693678429104886
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 13 13:51:24 UTC 2028
-------------------------------------
Next palindrome will be 941149
predicted to happen at this time:
Tue Mar 17 23:46:36 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 03:31:18 UTC 2026
