=====================================
Bitcoin Block Halving prediction
=====================================
bc=949041
gbt=1231006505
bbt=1778568487
This is average time to mine a block
(1778568487-1231006505)/949041
bts=576.9628551739543666139117
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 11:14:39 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 08:19:29 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 14:08:03 UTC 2026
