There are some sites where hard to earn few bits and others are easy to earn few dollars.
I think there is hardly any site which gives you 0% house edge. If you ask my view, i will suggest to use wealthydice.com as it is run by a trusted member and there is high chance of win there
If any trusted member runs the website means your funds are safe but that doesn't mean that your winning chances are better on that site. Because in gambling if you want to win money then you should be lucky otherwise no way you can earn any money. There are many other trusted sites on this forum to consider for gambling.
