Thanks for the comment. As for your concerns, we are thinking to do a smart contract on the blockchain in the future so that users are able to verify them. As for min and max bet, yes we have them and you can see how much it is for each type of coin in the bot. So basically, you dont need to manually key in the amount, there are a few options to tap on. As of now for the beginning, there is no house edge but all that will be implemented in the future should this take off.
In my opinion, I think those things that should happen in the future are essential things that should have been put in place from the first place even before launching. The entire blockchain is based on transparency and this is one unique way to build trust in any service you are rendering. If you are launching a service that this is not inbuilt, how else do I have the assurance that I am not being cheated if there is no way to verify it. I think you need to move the timeline of that "future" closer if the business would would live to enjoy the patronage that would sustain it into that future.
