=====================================
Bitcoin Block Halving prediction
=====================================
bc=962912
gbt=1231006505
bbt=1786983007
This is average time to mine a block
(1786983007-1231006505)/962912
bts=577.3901712823484572334156
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 15:52:42 UTC 2028
-------------------------------------
Next palindrome will be 963369
predicted to happen at this time:
Thu Aug 20 17:27:54 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 14:12:46 UTC 2026
