=====================================
Bitcoin Block Halving prediction
=====================================
bc=957587
gbt=1231006505
bbt=1783788506
This is average time to mine a block
(1783788506-1231006505)/957587
bts=577.2649625935162094763092
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 03:21:32 UTC 2028
-------------------------------------
Next palindrome will be 957759
predicted to happen at this time:
Sun Jul 12 20:23:15 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Sat Jul 11 18:53:30 UTC 2026
