=====================================
Bitcoin Block Halving prediction
=====================================
bc=947366
gbt=1231006505
bbt=1777604228
This is average time to mine a block
(1777604228-1231006505)/947366
bts=576.9651286143595882060489
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 11:54:27 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 16:20:05 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Sat May 2 03:38:00 UTC 2026
