Signature campaign is good for gaining trust but adding more promotions and rewarding customers is a must since it's what attracts gamblers the most and incentivize them to join new casinos.
Not really we have one casino here with 2 signature campaigns but the community did not trust them,
You are right but the said casino (wan't mention their name here) had a bad reputation even before they start their sig campaign. It's a bit different with new casinos. Other than gaining exposure, running a high paying campaign for a long time will prove you are here to stay. A business which spends a lot of money on advertising is unlikely to scam (small amounts, ofc).
I would like to suggest maybe you could create something like in-built coin exchange? As we are all aware you accept different kinds of BEP-20 coins including BNB, SHIB, USDT and many others but I would like to know if maybe in the future you would have an in-built exchange of coins like other gambling sites do?
Not sure there are many casinos which have in-built exchange! Most of them refuse to add it because it can be abused in many different ways.
But they can add some restrictions before one player can use the internal exchange like you need to achieve level X or wagered this amount. Anyway, what I noticed here is that a lot of exchanges are not having their internal exchange especially those who have a long list of alts in their payment method. But it is indeed good if the casino has one because some players do want to avoid high tx fees like for example in btc.
