Please, understand I warned you guys, this is a scam site under the veil of trust and honesty. My last straw was this past run up to 500, I had a long in for 2 btc 10x from 289.00 I was making crazy profit on it, closed out, start another for 4btc long from roughly 340. Making crazy profit and had a closeout for 480, as i always make a crazy high number not expecting to get it, but just in case for times like this. Then the site went down. We will see when it comes back if I got my profit. Highly doubt it. More than likely they don't have enough btc to pay out the bids they set up. Really sad if you ask me. Lesson learned, Coinarch is a scam site trying to be honest.
