=====================================
Bitcoin Block Halving prediction
=====================================
bc=969051
gbt=1231006505
bbt=1790629909
This is average time to mine a block
(1790629909-1231006505)/969051
bts=577.4957422305510952972595
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 22:40:11 UTC 2028
-------------------------------------
Next palindrome will be 969969
predicted to happen at this time:
Mon Oct 5 00:27:30 UTC 2026
-------------------------------------
Current mining epoch number is 480.
The next fortnight happens in block
969696 and probably around this time:
Sat Oct 3 04:39:53 UTC 2026
