=====================================
Bitcoin Block Halving prediction
=====================================
bc=955940
gbt=1231006505
bbt=1782740443
This is average time to mine a block
(1782740443-1231006505)/955940
bts=577.1631701119629767945929
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Mar 18 21:40:10 UTC 2028
-------------------------------------
Next palindrome will be 956659
predicted to happen at this time:
Sat Jul 4 08:57:03 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Fri Jul 10 15:48:53 UTC 2026
