=====================================
Bitcoin Block Halving prediction
=====================================
bc=937954
gbt=1231006505
bbt=1771844870
This is average time to mine a block
(1771844870-1231006505)/937954
bts=576.6144058083809990884424
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Mar 12 05:36:47 UTC 2028
-------------------------------------
Next palindrome will be 938839
predicted to happen at this time:
Sun Mar 1 08:52:53 UTC 2026
-------------------------------------
Current mining epoch number is 465.
The next fortnight happens in block
939456 and probably around this time:
Thu Mar 5 11:42:24 UTC 2026
