=====================================
Bitcoin Block Halving prediction
=====================================
bc=962840
gbt=1231006505
bbt=1786943877
This is average time to mine a block
(1786943877-1231006505)/962840
bts=577.3927076225461940237276
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 16:37:05 UTC 2028
-------------------------------------
Next palindrome will be 963369
predicted to happen at this time:
Thu Aug 20 18:08:37 UTC 2026
-------------------------------------
Current mining epoch number is 477.
The next fortnight happens in block
963648 and probably around this time:
Sat Aug 22 14:53:30 UTC 2026
