can someone please explain how is the freebitco.in lottery fool proof?
Can you explain how we can predict the hash of a Bitcoin block that hasn't been mined yet?
You can't predict the outcome of the hash, but as soon as it comes out, you can allot the winning tickets to your own accounts within a matter of second ones the block cokes out.
As no one knows the "Ticket Number" which was alooted to him, the game can be easily riggged.
