Just wanted some clarification on this, what exactly does this guy trying to make anyway? doesnt directbet refunded his bet ?latest news that I have read was about signing message from an address so that directbet would refund his bet however it seems this guy is keep on pushing things around here and feel unsatisfied
the guy who claimed deliberately double spending his transaction to directbet want to cheating .
double spend called as a race attack means the transaction can be invalidated.
so this is pretty clear to me , he trying to cheat.
there is no double spend when nadal lose like DB claim.
