Furthermore, I think that having the ability to set an automatic betting algorithm directly on your site would go a long way in raising the transaction volume for your dApp. Something like a simple Martingale that doubles the bet on a loss and reverts back to a set base bid amount on a win would be great. This way, users could just fund a Steem account with their risk capital, turn on the bot and let it run. Not having to enter the credentials each time is key. Maybe you could work something out with @yabapmatt to have it work with Keychain or something.
