There are a lot of casinos online, we even see new casinos coming to the markets each week here on the forum. But if we divide the normal/land casinos with online casinos, i think those places have a bigger wager in total than the online casinos. Just think about Las Vegas, can you imagine how much is the total wager just in that city? We know is the biggest gambling city in the world, but the point is, the users wager there more than the total wager from online casinos in the same period of time.
Don't you think that's a little biased because Vegas, as we know, is a gambling hub and so it's expected that land based casinos will be wagering a lot more than online casinos in that area.
On the other hand, if we compare the total wagering of all land based casinos with the total wagering of online casinos then I guess online casinos will be on the top.
I don't have the numbers but that's what I am guessing.
