=====================================
Bitcoin Block Halving prediction
=====================================
bc=929402
gbt=1231006505
bbt=1766652463
This is average time to mine a block
(1766652463-1231006505)/929402
bts=576.3333645361592334003656
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 8 19:38:34 UTC 2028
-------------------------------------
Next palindrome will be 929929
predicted to happen at this time:
Sun Dec 28 21:09:50 UTC 2025
-------------------------------------
Current mining epoch number is 461.
The next fortnight happens in block
931392 and probably around this time:
Wed Jan 7 15:22:46 UTC 2026
