=====================================
Bitcoin Block Halving prediction
=====================================
bc=922690
gbt=1231006505
bbt=1762577202
This is average time to mine a block
(1762577202-1231006505)/922690
bts=576.1091167032083330172289
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 02:14:13 UTC 2028
-------------------------------------
Next palindrome will be 923329
predicted to happen at this time:
Wed Nov 12 11:02:15 UTC 2025
-------------------------------------
Current mining epoch number is 457.
The next fortnight happens in block
923328 and probably around this time:
Wed Nov 12 10:52:39 UTC 2025
