=====================================
Bitcoin Block Halving prediction
=====================================
bc=959839
gbt=1231006505
bbt=1785154027
This is average time to mine a block
(1785154027-1231006505)/959839
bts=577.3332242873812302050341
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 20 23:16:07 UTC 2028
-------------------------------------
Next palindrome will be 959959
predicted to happen at this time:
Tue Jul 28 07:21:46 UTC 2026
-------------------------------------
Current mining epoch number is 476.
The next fortnight happens in block
961632 and probably around this time:
