Hi Jack, it's nice to meet you. I'm constant client of 247exchange and I really like everything except your buying limits with credit cards. I understand your risks, but maybe there is a way to make the limit grow a bit faster? And what about higher than max limit from

What I like most, is that your service do not hold our money, and that bitcoins are instantly delivered to my bitcoin address after the purchase. That's really a great approach! I also want to suggest you add more altcoins like Dash (ex Darkcoin) etc, I would love to buy some with my credit card of cash!
