It doesnt necessarily for each gambling site would post up some ANN thread on this forum but we know that it would be more better if they able to do so.
Of course, it's easier to support and see people's feedback if they have an ANN thread in the forum, and I think it would give more exposure to the site as this forum have millions of users, and since the market is bullish now, there should be a significant demand on gambling too.
About Cryptobet.com then i dont see any feedbacks on this one even if trying out some google search on where its really hard to make up some judgement basing of on our intuition
or presumption without any hard evidences.
Did try to check out their twitter
https://twitter.com/cryptobetcom which it doesnt really have any user interaction at all.So it wont be a surprising thing that no one havent heard of this sites existence.
But they have almost 2500 followers, if these people are real followers, then I guess they have some bettors.
Improvement is necessary for them, their marketing in different angles should be improve, especially in social media and if they can do in this forum, it's better. I hope our campaign managers would try to contact them and see if they could run a marketing campaign here.
