=====================================
Bitcoin Block Halving prediction
=====================================
bc=947968
gbt=1231006505
bbt=1777956784
This is average time to mine a block
(1777956784-1231006505)/947968
bts=576.9706382803657081613428
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:30:52 UTC 2028
-------------------------------------
Next palindrome will be 948849
predicted to happen at this time:
Mon May 11 02:04:55 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 16:11:13 UTC 2026
