=====================================
Bitcoin Block Halving prediction
=====================================
bc=975747
gbt=1231006505
bbt=1794634187
This is average time to mine a block
(1794634187-1231006505)/975747
bts=577.6365229546973193898424
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 24 15:43:51 UTC 2028
-------------------------------------
Next palindrome will be 976679
predicted to happen at this time:
Fri Nov 20 11:02:24 UTC 2026
-------------------------------------
Current mining epoch number is 484.
The next fortnight happens in block
977760 and probably around this time:
Fri Nov 27 16:29:29 UTC 2026
