=====================================
Bitcoin Block Halving prediction
=====================================
bc=942736
gbt=1231006505
bbt=1774757049
This is average time to mine a block
(1774757049-1231006505)/942736
bts=576.7786180026879182635241
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Mar 14 05:30:30 UTC 2028
-------------------------------------
Next palindrome will be 943349
predicted to happen at this time:
Thu Apr 2 06:16:54 UTC 2026
-------------------------------------
Current mining epoch number is 467.
The next fortnight happens in block
943488 and probably around this time:
Fri Apr 3 04:33:06 UTC 2026
