=====================================
Bitcoin Block Halving prediction
=====================================
bc=932361
gbt=1231006505
bbt=1768465674
This is average time to mine a block
(1768465674-1231006505)/932361
bts=576.4490283816800770516172
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Mar 10 05:22:41 UTC 2028
-------------------------------------
Next palindrome will be 933339
predicted to happen at this time:
Wed Jan 21 21:04:01 UTC 2026
-------------------------------------
Current mining epoch number is 462.
The next fortnight happens in block
933408 and probably around this time:
Thu Jan 22 08:06:56 UTC 2026
