I saw that in interface exist a place for a ETH and BTC balance, so you planning allow play games using another currencies or it will be automatically converted?
It would be nice, three wallet and converter like additional feature to the project. You shouldn't think about this, fill up a purse and play.
Here appear a question about prices on currencies. If they will provide a converter from where they will take a prices? AVG between exchanges or they will convert that you want to convert on exchange that they will make a deal and will return back resurt of operation?
