=====================================
Bitcoin Block Halving prediction
=====================================
bc=929832
gbt=1231006505
bbt=1766906188
This is average time to mine a block
(1766906188-1231006505)/929832
bts=576.3397115395990462803535
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 8 21:29:38 UTC 2028
-------------------------------------
Next palindrome will be 929929
predicted to happen at this time:
Sun Dec 28 22:48:12 UTC 2025
-------------------------------------
Current mining epoch number is 461.
The next fortnight happens in block
931392 and probably around this time:
Wed Jan 7 17:01:17 UTC 2026
