When it comes to using a new gambling site you have to be sure about the fairness of their game result because some new and old gambling sites choose to cheat. I don't say the OP site does
The cost of their withdrawal fee, time span they always process every withdrawal request, and level of site bankroll.
The country where they got their license and their rules and regulations.
If all these are not done appropriately then don't use them, if it's just you not having luck why not try another but it is always better to use an old reputable or new projects that's have a campaign on the forum.
