Holytransaction is probably one of the top wallet services and trading site around, even though nobody has heard about them especially newbies because their promotion has been lacking in recent days.

I haven't specifically used the trade operation on their site but have used their multicoin wallet.

It does seem like that they are paying out in Entropay virtual debit cards. I mean, you can definitely trust the site no doubt but consider the rates. They aren't going to be the best you'll get for your coin and add up all the fees, not worth imo. Sell it for cash and you'll get more.
