=====================================
Bitcoin Block Halving prediction
=====================================
bc=922823
gbt=1231006505
bbt=1762664307
This is average time to mine a block
(1762664307-1231006505)/922823
bts=576.1204758437145111093773
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 05:33:00 UTC 2028
-------------------------------------
Next palindrome will be 923329
predicted to happen at this time:
Wed Nov 12 13:57:03 UTC 2025
-------------------------------------
Current mining epoch number is 457.
The next fortnight happens in block
923328 and probably around this time:
Wed Nov 12 13:47:27 UTC 2025
