=====================================
Bitcoin Block Halving prediction
=====================================
bc=965981
gbt=1231006505
bbt=1788820061
This is average time to mine a block
(1788820061-1231006505)/965981
bts=577.4575054193556401672080
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 11:31:03 UTC 2028
-------------------------------------
Next palindrome will be 966669
predicted to happen at this time:
Sat Sep 12 12:49:11 UTC 2026
-------------------------------------
Current mining epoch number is 479.
The next fortnight happens in block
967680 and probably around this time:
Sat Sep 19 06:59:21 UTC 2026
