Or, are you buying and selling btc? (what license do you have for that from curacao?)
If i transmit 1btc to you today. i get $825 in my account.
Tomorrow, btc is worth $1.
I can then easily cash out using moneybookers my $825?
Also, imagine that i wagered with betsoft, whom you will be paying in USD (20%), or are you paying them in BTC?
Are you really sure about your setup if you allow btc and usd. huge risks..
You cant make deposits in BTC and withdraw in USD. If you make a deposit in BTC you can only withdraw BTC.
