=====================================
Bitcoin Block Halving prediction
=====================================
bc=965935
gbt=1231006505
bbt=1788786395
This is average time to mine a block
(1788786395-1231006505)/965935
bts=577.4501519769425717645889
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 09:22:22 UTC 2028
-------------------------------------
Next palindrome will be 966669
predicted to happen at this time:
Sat Sep 12 10:50:43 UTC 2026
-------------------------------------
Current mining epoch number is 479.
The next fortnight happens in block
967680 and probably around this time:
Sat Sep 19 05:00:45 UTC 2026
