Hello guys, I'm new here

I will launch my first casino in a few months and I was curious how do you advertise it? How much bankroll you had when you opened your first casino? Have you learned from your mistakes and if yes, what mistakes cost you a lot of money?
I appreciate every answer and thank you!
You need to use viral advertising.
Allow users to independently distribute advertising information on social networks. This is the most efficient option. Advertising in the form of short videos can give a very good result.
Videos should be very short because it is difficult for a modern viewer to process large amounts of information. Short videos are better remembered.
At the same time, advertising should not be banal. The plot of the video should be original and unusual. The director must be a very creative person.
