=====================================
Bitcoin Block Halving prediction
=====================================
bc=947451
gbt=1231006505
bbt=1777652586
This is average time to mine a block
(1777652586-1231006505)/947451
bts=576.9644066401253045009140
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 11:41:48 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 16:08:41 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Sat May 2 03:26:36 UTC 2026
