=====================================
Bitcoin Block Halving prediction
=====================================
bc=948063
gbt=1231006505
bbt=1778004454
This is average time to mine a block
(1778004454-1231006505)/948063
bts=576.9631048114895196948729
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 11:19:02 UTC 2028
-------------------------------------
Next palindrome will be 948849
predicted to happen at this time:
Mon May 11 00:05:47 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 14:12:00 UTC 2026
