=====================================
Bitcoin Block Halving prediction
=====================================
bc=929929
gbt=1231006505
bbt=1766964235
This is average time to mine a block
(1766964235-1231006505)/929929
bts=576.3420149903756196702977
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 8 22:09:57 UTC 2028
-------------------------------------
Next palindrome will be 930039
predicted to happen at this time:
Mon Dec 29 17:00:32 UTC 2025
-------------------------------------
Current mining epoch number is 461.
The next fortnight happens in block
931392 and probably around this time:
Wed Jan 7 17:37:03 UTC 2026
