Thanks for the support and understanding. You can see I'm honest with you - you cannot pay with credit card while making masspayment. It is used for big deals (eg. 150k euro) and it cannot be so easily reversed, as you think. What's more they've made recently an update telling that there is no 0% chances of getting your money back and there is no protection for all transfers made with this option, because it's simply option for wholesale deals and serious traders.
If anyone is willing to exchange some cash via PayPal hit me. As i told you, it doesn't have to be 15 BTC at once, it can be 2-5 BTC at first, then second part, then third...
I'm just looking for trusted partner to exchange.
