maybe you need to realize that none of us have any idea what goes on behind the scenes at directbet. there is NOTHING that prevents them from altering the hidden secret.
ever wonder why your bigger bets seem to lose more?
Read the link. The secret is hashed and presented to you
when you order your bet. When you click "place bet" and are given the address to send to, this is when the secret is created. So it's created
before you even send funds. Lookout for the hashed secret ID next time.
There clearly is prevention from them altering the secret, they are the biggest bitcoin book for a reason and some of the most knowledgeable people on provable fairness here at BCT have evaluated their site long & hard and found no problems.
