I have no idea about Betano, but I always see Bet365 on different social media or online video-sharing platforms. Well, maybe I have not just bumped into it.
Oh, and since I am mostly here in the forum, I just know the names that are here. I don't go too far when using a gambling site because I know it can be trusted once they made a reputation here in the forum. Regarding those revenues, I would not be surprised by the numbers. Betting platforms with sports betting are really big now, especially with the popularity of football, all thanks to many social media influencers who really hyped the stars of the sport.
Here in Brazil, in practically all soccer championships, and in practically all matches, there are advertisements for betting companies
Not only on the jerseys of both teams, but also on the field, on billboards, in TV commercials, etc
There are many of them, and most of the time they hire a famous player to be the main name of the company here in Brazil
So they are very popular here, even if they don't advertise here on the forum, or even if they don't operate in other countries
