I am curious to know who are their targeted audience and at what age group. In general gambling people target countries like thailand more but probably this is not the case with crypto. Do they target nerds or total dumbs? How efficient they are between their marketing tactics?
In my opinion, crypto casinos are not operated by targeting people of any particular country or age. It is almost open to everyone but in some cases preferred over 18s, depending on the casino establishment. However, most casinos do not target a specific country, because they know that to operate a casino, they have to operate globally, otherwise the organization may face losses.
I am certain that they have their own targeting groups for smart ads, as it would just cost more not to do filter them via algorithms. They can easily form target audience just by looking at existing users and their interests and activity on the net. Then they can pick most profitable / loyal users and cross check their interests, history and activity, and just target to similar users.
Picking a demograph that is highly susceptible has become easier, as there's so much data from people out there for sale and i am pretty sure they can form scarily accurate profile from me too.
And with right target group, sometimes all they to register is slightly aggressive advertisement feed.
And according to traffic stats i've been reading lately, referral links have been pretty good way to get new people in, and it's a kind of guerrilla marketing as well, as those people are getting percentages from the income so they have an incentive to advertise, which will cost less to casinos then huge public banners in the sport arena.
