Actually they can do whatever they want. Getting a collaboration with celebrity or signing a professional athlete for promotion was just an example. They can hire bloggers, give flyers, run an ad on tv, lots of things. My claim is to their "daily challenge" that they run for years. Now they have telegram game and try to join tap-game-hype. But that is it. Same promotion methods over and over again. Maybe it is time for something new?
It's worth noting that gambling projects face a lot of restrictions in many countries when trying to promote their brand. Yes, there are many other ways to promote, but if we talk about advertising on TV, I think there are only a few countries where gambling projects can do it.
By the way, isn't brand promotion and attracting new audiences with a tap app during the hype time something new? Since the Betfury tap app has been running for almost three months now and the Betfury team often emphasizes it in its social networks, I think it's an effective marketing method for them at the moment.
