=====================================
Bitcoin Block Halving prediction
=====================================
bc=949186
gbt=1231006505
bbt=1778655871
This is average time to mine a block
(1778655871-1231006505)/949186
bts=576.9667789381860476386634
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 12:23:19 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 09:21:36 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:10:09 UTC 2026
