Hmm, no offense but I am just thinking that maybe you will used a hacked credit card to purchase those? And if that's the case, you may face some problems regarding your trades. Tell me, how would your service work? I've seen a lot of them before, one of them being purse.io. Also, you're a newbie, and as always, no one will trust a newbie on handling such trades unless the user already built some reputation around the forum.
