=====================================
Bitcoin Block Halving prediction
=====================================
bc=956793
gbt=1231006505
bbt=1783257882
This is average time to mine a block
(1783257882-1231006505)/956793
bts=577.1894232196272133813548
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 05:19:36 UTC 2028
-------------------------------------
Next palindrome will be 957759
predicted to happen at this time:
Sun Jul 12 00:17:26 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Fri Jul 10 22:47:53 UTC 2026
