i think i can agree on this one, if he wants, he can check the number of online people in betfury. though it is not really a measure of how many players are active, but you will have an idea how many are visiting the casino. also, they have in-house promotions. if he will try playing the $150 funfury competition held every 12h, you will see that there are thousands of players in this contest alone. you can see your place once you start playing using their free funfurytoken. so right now, i don't think sig campaign is their priority. they may hold it again if they are seeing very good advantage of it.
They already relaunched it some time ago and will probably relaunch it one more time when there is a new big event! I like the Funfury competition in fact, it is free and I already ended 3 times in the top 150. Most of the times I get busted right away, but some days everything goes right and I keep wagering with the FUNtokens.
I think that's quite good efficient way of using signature campaigns as well. Like for example let's say you have 200 people wagering at any given time, but if you do competitions there are 500, if you have no competition but signature campaign you have 500 again, but if you have competition AND signature together, it's going to be over 1000 people for sure.
This means that you are getting the best bang for buck as a casino and that's an important thing. I can't talk about much because I do not have their data, but I am sure that they are doing as well as they possibly could and that's going to be the key, the data, they have it and they can make a decision based on that.
