=====================================
Bitcoin Block Halving prediction
=====================================
bc=960255
gbt=1231006505
bbt=1785413749
This is average time to mine a block
(1785413749-1231006505)/960255
bts=577.3535848773660357238069
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 21 05:12:26 UTC 2028
-------------------------------------
Next palindrome will be 961169
predicted to happen at this time:
Wed Aug 5 14:50:50 UTC 2026
-------------------------------------
Current mining epoch number is 476.
The next fortnight happens in block
961632 and probably around this time:
Sat Aug 8 17:06:04 UTC 2026
