I don't trust anything on Ethereum right now. They seem to get hacked pretty easily. Edgeless is also taking out a lot of the profit. I believe its 60% goes to the team and the other 40% is put in a lottery and you get some sort of rewards based on the lottery. Supposedly the 60% goes to making the site better, but I am sure a lot of it is being put in their pockets. I am not a big fan. Also being edgeless with no edge and putting a cap on how much people can bet is not profitable when it comes to gambling. If some whale wants to play whatever he wants and plays poorly that is where the profits come in. THey can't afford to handle a big bank roll so I am not sure they will succeed.

VDice  I don't know much about but I didn't care for the website when I went to try to play on it...
