=====================================
Bitcoin Block Halving prediction
=====================================
bc=964545
gbt=1231006505
bbt=1787991879
This is average time to mine a block
(1787991879-1231006505)/964545
bts=577.4585908810984649773053
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 11:50:02 UTC 2028
-------------------------------------
Next palindrome will be 965569
predicted to happen at this time:
Sat Sep 5 04:39:56 UTC 2026
-------------------------------------
Current mining epoch number is 478.
The next fortnight happens in block
965664 and probably around this time:
Sat Sep 5 19:54:15 UTC 2026
