=====================================
Bitcoin Block Halving prediction
=====================================
bc=966888
gbt=1231006505
bbt=1789343068
This is average time to mine a block
(1789343068-1231006505)/966888
bts=577.4567328824715143103293
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 11:17:31 UTC 2028
-------------------------------------
Next palindrome will be 967769
predicted to happen at this time:
Sat Sep 19 21:03:27 UTC 2026
-------------------------------------
Current mining epoch number is 479.
The next fortnight happens in block
967680 and probably around this time:
Sat Sep 19 06:46:53 UTC 2026
