Re: Trade simulator 2.0 [Fully automated paper trade competition]
Looks like I have the same -100 bug. For a minute I saw a dozen other traders with -100 (including Afrikoin), now it's just me. 
Hey - I just rolled back your trade to your previous one. We're looking into this and trying to find the root cause of the issue, bear with us please. For now you can continue with the trade you were trying to perform
At the time it showed anyone with a btc balance as -100% p/l because the coindesk api was reporting a price of 0.00. I am going to look into devising our own index price internally so that this problem goes away permanently. We will continue with a testing period before we do a reset of the scoreboard. I want this to be perfect, and I want people to remain interested in the game, so I want these kinds of things fixed. Priority one is getting the issues fixed, then roll out new features that are at least independent of this particular issue.
edit:
if you see the price at 0.00, DO NOT MAKE A TRADE. It WILL result in a complete loss. Wait a minute, and refresh and all should be back to normal.
