I'm new to the Bitcoin currency and had to pay for my education. I joined coin.mx and made the mistake of trading in the "simple" mode and was paying $279.40 when the market was about $240.00. I don't know why they have two modes, "simple" and "trading", unless they are purposely trying to take advantage of beginners, like myself. They even processed a transaction before I confirmed it. Even scamadvisor.com rates them as very low trust rating, so if you are a newbie,
be careful when dealing with coin.mx!
