=====================================
Bitcoin Block Halving prediction
=====================================
bc=954963
gbt=1231006505
bbt=1782194171
This is average time to mine a block
(1782194171-1231006505)/954963
bts=577.1816173175114454576298
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 03:03:00 UTC 2028
-------------------------------------
Next palindrome will be 955559
predicted to happen at this time:
Sat Jun 27 05:29:31 UTC 2026
-------------------------------------
Current mining epoch number is 473.
The next fortnight happens in block
955584 and probably around this time:
Sat Jun 27 09:30:00 UTC 2026
