As the saying goes, the more the merrier, so hopefully Wolfbet is already have this in the pipeline, not just IPL for any other sports that might not be well known today but there is a big potential for it in the future. Maybe some casinos have listed it and so in the beginning their could be jus small market for it. But once it becomes big then they for sure will make a lot of profits as they could be one of the earliest casinos that have it. So I do agree that marketing or promoting it should be constant and it should continue until they see some results. Gambling industry is a billion dollar business, so just imagine if you can get a piece of the pie? Like in some regions in the world, South Asia and SEA countries are a big market. How do I know? Because I lived on one of those nation.
Yes, gambling is a business with a huge turnover, so to reach users, they must promote themselves. It's certainly expensive, but I think the rewards will outweigh the outlay. We can see large, well-known casinos today doing the same thing: massive promotions, but they're also effective.
When there's a match on, there's also a large pool of people interested in gambling. I remember when there was a football match in my neighborhood, but it was limited to my neighborhood. There were always people betting, even if it was just individual bets, just for treats at a gathering place.
