When would it be possible to cash out bets? Last time I placed a bet but wanted to change the bet but this seems not to be possible?
The last time they indicated (I believe) that this is not possible yet. Maybe they will improve the system and make it possible.
They also have to think about integrating Ethereum as deposit method, this coin is getting more and more popular and raises in market value as well.
If they want to get more players, then for sure they have to take a look at this. I think that most cryptocurrency based bookmakers also have the option to make deposits with this. Of course the bitcoins is number one to deposit but Ethereum is winning market cap.
