yes it is one thing if double spend is malicious
but they claim that double spend AFTER nadal lose first set... but TX they provide shows input that is spent over 1 day previous. So it is not possible to spend malicious like they say nor did it occur after nadal lose first set. So if it was malicious you would not do it this way with transaction that could never confirm, you would actually do malicious.
Then they steel bet that comes from they casino coin account.
They just see quick chance to make quick btc. Why it is voted D and why major players will avoid it. They win in short but faith they lose long run.
