=====================================
Bitcoin Block Halving prediction
=====================================
bc=958035
gbt=1231006505
bbt=1784048707
This is average time to mine a block
(1784048707-1231006505)/958035
bts=577.2666183734222931079834
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 03:50:31 UTC 2028
-------------------------------------
Next palindrome will be 958859
predicted to happen at this time:
Mon Jul 20 05:12:54 UTC 2026
-------------------------------------
Current mining epoch number is 475.
The next fortnight happens in block
959616 and probably around this time:
Sat Jul 25 06:36:05 UTC 2026
