=====================================
Bitcoin Block Halving prediction
=====================================
bc=922462
gbt=1231006505
bbt=1762427818
This is average time to mine a block
(1762427818-1231006505)/922462
bts=576.0895699881729673710490
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 5 20:32:09 UTC 2028
-------------------------------------
Next palindrome will be 923329
predicted to happen at this time:
Wed Nov 12 06:01:27 UTC 2025
-------------------------------------
Current mining epoch number is 457.
The next fortnight happens in block
923328 and probably around this time:
Wed Nov 12 05:51:51 UTC 2025
