=====================================
Bitcoin Block Halving prediction
=====================================
bc=949340
gbt=1231006505
bbt=1778746016
This is average time to mine a block
(1778746016-1231006505)/949340
bts=576.9681400044873233116446
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 12:47:08 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 09:43:09 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 15:31:41 UTC 2026
