=====================================
Bitcoin Block Halving prediction
=====================================
bc=948843
gbt=1231006505
bbt=1778456912
This is average time to mine a block
(1778456912-1231006505)/948843
bts=576.9656624271218451083634
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 12:03:47 UTC 2028
-------------------------------------
Next palindrome will be 948849
predicted to happen at this time:
Mon May 11 00:46:13 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 14:52:29 UTC 2026
