=====================================
Bitcoin Block Halving prediction
=====================================
bc=956877
gbt=1231006505
bbt=1783312595
This is average time to mine a block
(1783312595-1231006505)/956877
bts=577.1959330238546606777457
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 19 07:13:31 UTC 2028
-------------------------------------
Next palindrome will be 957759
predicted to happen at this time:
Sun Jul 12 02:01:21 UTC 2026
-------------------------------------
Current mining epoch number is 474.
The next fortnight happens in block
957600 and probably around this time:
Sat Jul 11 00:31:47 UTC 2026
