I have decided to stay annoymous for the safety of your bitcoins that will be invested in the bankroll.
How does that work, exactly?
Since the bankroll is publicly known, it would be a risk to the investors if criminals can easily find out who the site operator is. For example, there was a case where a member of this forum had his house broken in just to have his asic miner stolen, so it was definitely a highly targeted heist. Just-dice has $5 Million worth of bankroll in his computer, which would make the site operator a good kidnap target for the criminals to point a gun at his head to transfer all the bitcoins to them, then run off...
Its looking good and is a great idea.
A couple of UI notes: I'm having some rendering issues on an iPhone 4S (iOS 6.1.3) The longer pop over windows (e.g. "invest" and username) that require vertical scrolling are frequently resetting their scroll position to the top and flashing on and off making text input difficult. (e.g. when the 'learn more' option is opened under 'invest'). It may have something to do with the text crawl across the top...?
Also, the payout text field and win percentage chance text field in the middle of the screen are somewhat confusing. They are styled the same as all of the other elements on the screen yet they are the only ones that aren't active UI elements (they are read-only) which is inconsistent. Being the two biggest things right in the center of the screen, it can make the app seem broken for a new person who comes and taps them only to have nothing happen. Obviously it is a 'learn once' kind of deal, but maybe there is a design solution to those fields. Maybe don't make them look like buttons.
Thanks for the tips, I will fix those asap
