so you are already existing since 2015 do you have an old thread here why are you promoting your online casino software just now, when you are already live since 2015, I also did not see any testimonial coming from your clients, or a link to your clients, old and new, there should be clients names on your home page, to make your service legit.
This is a classic way to seem to be more trustable than what they are, personally I do not have any problem with a new company trying to make a name for themselves but when they seem to lie about their experience or the time they have been in the market then I cannot help to wonder in what else are they actually lying, as if they are willing to present conflicting information about how long they have been in the market then the people behind this are probably willing to lie about anything.
