Re: Try out our new Futures Exchange! (margin in testnet BTC)
This "five second trading" was just meant as an example of what you can do at our exchange that you definitively can't do elsewhere. Please feel free to do more traditional day trading 
Regarding your balance, it looks like you still have a long position of +0.2 mBTC. If you close this position (by sending a sell order) your balance shoud be unfrozen (+/- your profits).
Future tokens were just meant as a (small) thank you gift! If we do well these may be worth 100x-1000x in the future, but you don't need them for trading (in the future they'll give trading fee discounts na other benefits).
