=====================================
Bitcoin Block Halving prediction
=====================================
bc=960148
gbt=1231006505
bbt=1785361177
This is average time to mine a block
(1785361177-1231006505)/960148
bts=577.3631717577167710428277
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 08:00:12 UTC 2028
-------------------------------------
Next palindrome will be 961169
predicted to happen at this time:
Wed Aug 5 17:24:24 UTC 2026
-------------------------------------
Current mining epoch number is 476.
The next fortnight happens in block
961632 and probably around this time:
