I have checked, their bitcointalk, twitter and telegram were last active is april. Looks like they don't take their site very seriously. If it's still in development stage, isn't that the best moment for them to do their casino marketing,.But that's not what happened.
In my opinion, you are completely wrong. OP created this thread and provided the initial version of the website. He got a lot of opinins, advises and feedbacks, which will allow him to improve the website.
In my opinion, this is a very wise course of action.
Spending money now on marketing, in the moment that the website is not finished is pointless and would be a big mistake.
I advise you not to advise anyone else anymore.
