Looks good to me. But website seems amateur to me. Also Break Even In: 169 Days. seems not good roi.
Don't let the front-end fool you, we have a very secured system, but I have to agree that the front-end of the website is amateur. Our crew consists of programmers, we are not top-end web designers. But we are in the process of having a full web 2.0 front-end revamp.
About the break even, scrypt coins difficulty and profitability are very unstable, the rates you see on the calculator are updated every minute with data coming straight from our data centers. I've seen it vary from 90 days up to 210 days on difficulty spikes.
Well if its secure you should add more then just a pin and force redirect to ssl/https: quite of few people and myself included were redirected to just plain http connections.
Also how about adding a display kh/btc for current price, i had to ask someone in the chat box for the going price.
Also how about adding the chat function on all tabs not just the trade tab. Lastly no F2A yet? Your site looks like its growing and alot of btc are invested there needs to be protected more.
Lastly how about an daily or auto withdraw when xx amount of btc is reached. Don't want to become another 50btc.com mess where people left their btc on the pool just to have it hacked/lost their coins.
