=====================================
Bitcoin Block Halving prediction
=====================================
bc=949644
gbt=1231006505
bbt=1778929145
This is average time to mine a block
(1778929145-1231006505)/949644
bts=576.9762806101227300728166
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 15:09:36 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 11:52:02 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 04:46:55 UTC 2026
