=====================================
Bitcoin Block Halving prediction
=====================================
bc=944585
gbt=1231006505
bbt=1775904374
This is average time to mine a block
(1775904374-1231006505)/944585
bts=576.8642230564501273573819
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 06:28:36 UTC 2028
-------------------------------------
Next palindrome will be 945549
predicted to happen at this time:
Fri Apr 17 21:14:31 UTC 2026
-------------------------------------
Current mining epoch number is 468.
The next fortnight happens in block
945504 and probably around this time:
Fri Apr 17 14:01:52 UTC 2026
