=====================================
Bitcoin Block Halving prediction
=====================================
bc=941427
gbt=1231006505
bbt=1774009091
This is average time to mine a block
(1774009091-1231006505)/941427
bts=576.7861015393636050765432
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 07:41:28 UTC 2028
-------------------------------------
Next palindrome will be 942249
predicted to happen at this time:
Thu Mar 26 00:00:09 UTC 2026
-------------------------------------
Current mining epoch number is 466.
The next fortnight happens in block
941472 and probably around this time:
Fri Mar 20 19:30:46 UTC 2026
