=====================================
Bitcoin Block Halving prediction
=====================================
bc=937953
gbt=1231006505
bbt=1771843341
This is average time to mine a block
(1771843341-1231006505)/937953
bts=576.6133904221315757489173
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 05:19:01 UTC 2028
-------------------------------------
Next palindrome will be 938839
predicted to happen at this time:
Sun Mar 1 08:37:00 UTC 2026
-------------------------------------
Current mining epoch number is 465.
The next fortnight happens in block
939456 and probably around this time:
Thu Mar 5 11:26:30 UTC 2026
