=====================================
Bitcoin Block Halving prediction
=====================================
bc=941340
gbt=1231006505
bbt=1773957372
This is average time to mine a block
(1773957372-1231006505)/941340
bts=576.7844670528533230784593
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 07:12:52 UTC 2028
-------------------------------------
Next palindrome will be 942249
predicted to happen at this time:
Wed Mar 25 23:34:29 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 19:05:07 UTC 2026
