It is just hard to compete in the gambling industry especially if there is nothing special in the site.
The crash game by wedaddy is unique indeed but it is not enough, free faucet is good but it will not attract real players, the weekly giveaway is not attractive enough as well (at least for me).
They need to offer something special that can attract players from other casino to try and play in wedaddy.
Otherwise, players wont be willing to try wedaddy as most players have their own favorite place to play crash game already.
For this they may need to run a campaign. It can be a bounty or sig campaign which pays in BTC. They can also avail the forum advertisement which I think only done via auction. Other than those, they can also change or add more features as you said as some users may not be satisfied on what they are currently offering.
btw Signature campaigns too are one of the most effective strategies that new gambling sites can try to make their reputation increase and it has been proven in many crypto-gambling sites that run signature campaigns on this forum
